Sam was a big help. This is the first supplement that actually appears to have made a difference in my feet and my knees Sam helped negotiate a price that I think Ill be able to work with in the future but very difficult on fixed income so well see. Thank you.

I was very satisfied.

The guy I spoke with was courteous, he articulated very well and helped me get my order done in a timely manner.

Greater than expected...

I called to modify my autoship delivery schedule for my Instaflex Advanced subscription. Can't tell you how pleased I was to connect with Crystal in the USA! No foreign call center "experience" here. Crystal listened to my needs and responded instantly with a positive 'can do' spirit. She effortlessly got my autoship schedule setup to conform to my personal life schedule. If you call Instaflex, do hope that you get Crystal on the line! Kevin in Florida

They took almost $82.00 out of my account for their free advertisement.

I ordered the two weeks supply medicine that was supposed to be to be free. They charged me the shipping and handling like agreed.

Then today I found an almost $82 dollar charge from instaflex on my bank statement. I wasnt suppose to be charged anything but the shipping and handling.

User's recommendation: Don’t fall for the free samples gig.

Cancelation

I had canceled by subscription and still received the supplement

I was advised by the customer service representative to reuse the package, but they would not do that. So I had to send it out and spend fourteen dollars to have the product.Sent back and I want a credit as soon as possible

Yeah I've got to be the most deceitful and lioness company that has ever been you're so unorganized and you are constantly taking money for people that have not ordered things I want my money back

What happened is I will wait till I can speak to someone in person which is damn near impossible with you guys it's been going on for a week you keep taking money out of my account I'm not ordered anything and I can't seem I've done and had it supposedly canceled and I got my card again and tried to take more money out and I've done this three times and I'm not received the product yet and don't want the product because I tried it for 2 weeks and it didn't help

User's recommendation: Run run run away from this company is fast as you can They already rip off their product is no good plus they are constantly taking your money for something you do not receive and did not even order they're more pain than what the joint pain is My advice to everybody don't deal with them

I was unaware that I signed up for a subscription to instaflex. I'm sending this to tell you I want to cancel that subscription. Since I never wanted it in the first place.

Cancel subscription and never used

I never spoke to anyone. And I have never used any of the bottles after trying one. I have many unopened bottles and they keep sending them and billing me and raising the price charged on my credit card.

Hi Joshua - Our records show that your account now has your Apt number listed on your account. You have a package in transit to you as we speak and should arrive via USPS in the next few days. In regards to your next shipment, our records show that when you phoned in the agent updated your next shipment date to 5/17. If that is incorrect or you would like something different, please don't hesitate to reach back out to us.

I was charged but I never received my pills

I was told that I never put my Apt number on my address but if that was true how did I get the free trial 2 week supply delivered to me? I was told today that I will receive a bottle on March 25th and another one on March 31st 10 days from now. My Apt number is 104, please deliver to my door only.

Disappointed

The company just took my money and lied about the amount during the advertisement on the internet. They had an offer for $5.99 but charged my account $75.00.

Got product that I didn't order

AI Highlights
  • - I got a free sample and paid $5.99 shipping.
  • - I was auto-signed up for a subscription and charged $79.89.
  • - I returned; refund promised but not received.

I got a free sample of instaflex and all I had to do was pay shipping and handling which was 5.99. Then they automatically signed me up for a subscription with them tht i didn't do and then they charged my PayPal card 79.89.

For something that i didn't order. I called them they told me to send it back and they would refund my money. So I sent it back its been over a week. I also sent them a email and no response.

Ive contacted PayPal and explained everything to them. So im going to contact paypal again and open up a dispute.

User's recommendation: I wouldn't buy anything even if it's free from instaflex. They will sign you automatically for a subscription without your permission and also charge your card . Their not a good company i would stay away from them ive learned my lesson. Wont be no more.

To cancel future subscription

Canceled via Telephone call on 3/6/2026. No cancelation number given.

Suggest canceled numbers be given as proof so as to avoid any problems. Cancelation was very easy

User's recommendation: Give customer cancelation number as proof
