Photography Plan bought from Adobe store on Amazon not valid according to Adobe

Hi

I have just had the most bizarre, incomprehensible support call and have to ask for some sense from the community.

I received an email from Adobe yesterday saying my Photography Plan package was fraudulent and I have 5 days to resolve the issue. I used the online chat to get through this morning and got connected to "V" who was the opposite of customer service and actually hostile. 

I have been a genuine user of the 20GB Photography Plan since 2017 when I bought my first year via Adobe store on Amazon. I have bought this item 6 times since including two on Black Friday this year. I also added 3 months which came on with the purchase of a Logitech keyboard earlier this year. My Photography Plan shows as valid until December 2024. All valid all paid for.

'V' tells me that my software has decided it is fraudulent and gives me the first serial I bought from Amazon and entered in 2017. I explain that I have always bought them from Amazon's Adobe store and they always work. 'V' tells me that Amazon are not a recognised partner of Adobe and anything bought from them is invalid. 'V' doesn't have access to anything else on my account other than fraudulent serial and that is all there is to discuss. "Take it up with Amazon".

I ask if that means that the 3 years of Photography Plan I have on my account are lost and they answer yes "because you bought them from Amaszon". I ask what about the 3 months from Logitech that came with an expensive keyboard is that fraudulent too? Apparently it is invalid because Logitech are also not a partner of Adobe. So tough. End of conversation. End of account. I asked for a name and a full script of the conversation and that was it.

I have never had worse customer support than this from any company nevermind one I have been loyal to while everywhere I look people use pirated software.

Is this normal for Adobe? Are Logitech making up an offer regarding Adobe Photography Plan? Or did I just get the most useless, angry, mono-syballic CS rep who wants to lose Adobe loyal customers?

Thanks for any help. My next step is to use my family member at the Guardian to highlight this appalling service. Not that I suppose Adobe will care about their public image overly much.
