Completed Middleman Transaction

I bought this account few month ago. I saw that account was linked to a Google account after i bought the account.
He told me that it wasn't a problem because the Google was deleted and now someone is connected and he is using my account ....
I'm really disapointed and angry !!
Stop using my account or you need to refund me !!!
I sold many account here and elsewhere you can check my other nickename " Ezkimo" so you Can trust Me when i'm saying that !
