Communication from Adobe after Online Chat [Branched from Re: Non genuine redemption code]

Stick at them and get all the info you can to support your case.
It seems to me that Adobe as messed up big time.

I have the same issue. Between February and April 2021, I bought several pre-paid redemption codes for the Photography Plan from a company called Gamivo. About 2 weeks ago, I received an email from Adobe saying one or more of these were obtained fraudulently and therefore invalid. They want to cancel my account now. I had pre-paid subscription valid until February 2025, including a redemption code that was bought about 3 weeks ago from Amazon.co.uk (not a 3rd party). They are saying my Amazon redemption will also get cancelled as their system cannot remove a single redemption code. The complete account will need to be cancelled. They admitted that until recently they did not have a mechanism to identity these fraudulent codes. They are offering me 3-months of ‘free’ plan as compensation, but I will be losing so much money.

Any ideas what my options are ?

Thanks for any suggestions.

I will fill you all in with details i left out while this case was ongoing.
I normally buy my photography package via prepay from Amazon UK directly not a seller using the platform, I had purchased another year at the end of August as i knew it was due to run out soon (i messed this up as it was next year) but all was OK, I also ordered a new Logitech MX Keys Keyboard & MX Anywhere 3 mouse via Amazon UK and part of the promotional deal was either 1 month of all adobe products or 2 months of photography plan for free, I went with the 2 month extension on my photography plan, so i supplied a copy of my invoice to Logitech and they issued the redemption code to do this and all was OK until last week when adobe flagged up the use of a fraudulent code but didn't say which. 
I was constantly asked via webchat for a copy of my invoice for the redemption code used but they wouldn't say which code they wanted it for as i didn't get one the promotional redemption code, I eventually got through a line manager who told me the code and then worked out it wasn't any of the prepay codes leaving the so called fraudulent code coming from Logitech, So i explained to them the promotion and provided a copy of the keyboard and mouse invoice along with a link to the offer. if this hadn't been resolved in my favor i was told i would have lost all my active codes and was just short of 2 years worth approx £220. 
I have also contacted both Logitech & Amazon UK about this but i havent had any response from them yet.       

Adobe response.

Thank you for contacting Adobe.

We have investigated with your issue regarding the redemption code use in your account, the subscription will not cancel which was purchased from the Amazon, you can continue using the subscription without any interruption please ignore the email that you have received earlier.

The reason you were getting the notifications an email for cancel and fraud prevention is for the redemption code which you might have redeemed in your account which was invalid or purchased from unauthorized reseller/third party.
