Is there any way to get my deleted decks back?
I got an e-mail warning me my decks will get deleted soon. I have not used them lately and as I checked it seems they are all already deleted.
Is there any way to get them back working?
I tried the recover backup option, but it is not working in my case as I really have not used my decks for a while.
I would be happy to get them back.
Your account has not expired recently, so if your account is empty, it will have been empty for some time. Your only chance to recover the data is if you have a local copy: AnkiWeb account removal - Frequently Asked Questions
