Account got recovered by previous owner

I bought an account with Kunai and Lifeline Shock Sticks from this guy for a lot of money. Exactly 5 days later the account got recovered by its original owner. EA support basically told me that it was recovered from a previous account. I was stupid enough to put more money in the account while having it for those 5 days, so I lost those too. I am trying to reach him all day but the only answers I got was that I got hacked (Which I wasn't since even EA Support basically confirmed it and I even have screenshots of my conversation with them) and then he told me he would talk to the original owner of the account. 11 hours later nothing, I talk to him but he does not respond. I JUST saw that another guy had the same problem yesterday. I am hoping it is just a coincidence and not intentional. I am hoping for a refund or at the very least another similar account with the things I was looking for in that particular account and paid for. I will renew this review if and when I hear from the guy. Until then I would stay away from these accounts. For whoever wants more insight or does not believe me I do have screenshots and can provide them.
