I paid for this account, but later it was suddenly taken back and sold it to another buyer. Scam!

I bought it via paypal (for friends and family) and got it at first (it worked), but then after a few days it was forcefully taken back from my cell phone and it was sold to another buyer, I assume, because (the seller didn`t marked this account/thread as sold and has another seller-thread with the same account, so this seller sell the same account twice +) some other players had the same problem and they all bought the same account/picture/scouts that is from the same seller (but has changed names in other forum). I didn`t get a reply or an answer from my messages. Beware !!! This seller is a scammer !!!
