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

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

Trued too hard to not cancel automatic subscription

Original review Feb 10, 2026

Give us a break - why 199 characters? I disputed a charge I did not know about to occur after a trial period - customer service tried to get me to continue but after 14 days I still do not know about that so he said he would cancel - I will dispute with my credit card company

User's recommendation: Make sure if what you sign up for

Terrible Customer service

AI Highlights
  • - Cannot cancel subscription until email verification.
  • - Code must be used within 5 minutes.
  • - The code isn't sent to the email account.

I can't submit a message to cancel my subscription until my email address is verified. You have 5 minutes to use the code and verify your email address.

But they never send the code to your email account. I'm going to the BBB.

User's recommendation: Beware

Instaflex's reply dated Sep 24, 2025 to: Amber A Bmg's review

Hi Amber - We're very sorry to hear that you had an issue ordering. We still offer the sample of Instaflex for $5.99. When you purchase this sample, you are not obligated to buy anything else if you cancel your trial within the 18 day trial period. We do show that you attempted to place an order 4 times the other day and that your card was declined each of the times. If you would like to attempt to place an order again for a sample, you are more than welcome to do so. We also offer discount programs for Seniors and others if you would like to buy a full month supply but at a discounted price. Any one of our representatives will be able to tell you about this if you call in. You can also email us at support@instaflex.com and we can assist with this as well.

Hi Joyce - we're sorry if there was any confusion. When you called in the prompts you chose allowed you to cancel your account without having to speak with a live person. We're sorry if you were confused by this but we view this as a positive as you can interact with our company fast without having to wait for a live agent. As it stands now, your account was canceled within the trial period and you won't be shipped or billed anything else.

Cancel Instaflex subscription

I thought I was just ordering one bottle. However, it keeps coming so I must have signed up for a subscription. I would like to cancel that subscription now.

Hi Claudia - Your account was canceled within its trial period and you were not shipped or charged for anything other than the original trial. We're sorry if you were surprised by or confused by any aspects of the trial program. We show all the terms of the program on the checkout page, above the checkout button and require all customers to check a box stating they have read and agree to them before they can complete their order. We also include a copy of the terms in the email receipt, as you referenced. Should you need anything else, please don't hesitate to reach out to us directly.

You were not clear. You wrote at the end with little words, the next payment of more than $60 dollars after the first 14 days. I can NOT pay that

I cannot pay after 14 days about $65 dollars or whatever the price is. I have to cancel .

I cannot pay. I just wanted to prove it and if it really works, find a way to do the treatment.

You have not been honest. If I dont read the last.

Part you charge my credit card on something I didnt agree on

I will report this to my bank so no payments will be done.

You abused of me. I did not agree on that payment from the 14 days on.

I dont have how to pay that.

I hate this kind of companies that talk to nice but at the end are just ..
