(URGENT) Gta online deletes your car?

So in gta online I called the mechanic to have him bring my entity xf. When he finally shows up he brings a copy of another car in my garage. So I left the car there and went to my garage to find out that the car that was copied was not in the garage either. Next thing I did was leave the game to try to get both of my cars back. So when I got put into the next game the car that was copied was back, but the entity was replaced with the copy car. So I sold the copy and loaded myself into another game. And my poor entity's spot in my garage was completely gone. I called the insurance place but I got the thing that said they were all busy (meaning none of my cars needed to be replaced). So now what should I do, because I don't have enough money to buy another entity and I really want it back. I doubt I can get anything out of Rockstar because I am not signed up to social club. I had this happen once earlier but the car was destroyed and after loads of copied cars I got it back. Please help
