Was gifted the game two weeks ago, still can't play it. (My Steam is somehow linked to a deleted account)

I was gifted GTAV about two weeks ago by a friend. I spent 30 or so hours downloading it and when it was finally ready to play I was met by some lovely red-text that read: "This steam account is linked to another Socialclub, please use that one instead". Still wanting to use my actual SC account (the one with all the progress I have from X360 & XONE) I decided to search the forums for others with a similar problem, there was a lot. I read several posts on the R* forums about the issue and learned the only way to have a Steam account unlinked was to have the SC account it was linked to deleted (this info came from a R* support rep in response to another person with the same issue). Realising that my only hope to play the game was this, I submitted a ticket and waited. After a week of silence (not even an email) I tried logging in to the account I wanted to be deleted and I couldn't. They deleted it finally, and never even bothered to tell me. Excited, I launched Steam and tried to play GTAV. "This steam account is linked to another Socialclub, please use that one instead". My Steam was still linked to the account... the now DELETED account. ffs R*. I submitted another ticket immediately and received a copy/pasted response thanking me for my patients and was told to wait. It's been yet another full week and, nothing. No email and now the R* support twitter ignores me. I'm not told if my issue is being worked on or even if my issue is fixable at all. I'm just stuck here, with a $60 digital paper-weight that I can't play because R* forgot to unlink my Steam before deleting my account. Scratch that, over $120 worth of paper-weights. I have three R* games on my Steam that I can no longer play because of this, and all I get is silence. Cheers Rockstar, cheers. If anyone has any idea how I can fix this or even if this CAN be fixed please let me know. Any help at all would be greatly appreciated. Thanks.
