How many times must a new car go back for the same

I purchased my Eco Sport in Feb 2014. A couple of weeks later the cubbyhole was loose and the back windows were slipping. I called ford and took my car in. The assured me it was fixed. Not three months later the same problem occurred, the back windows were slipping. The service manager informed me they had a problem with the eco sports as his wifes windows also were slipping and I should bring it in again and leave it there and they will get hold of the plant overseas and see what could be done. Two days later I get a call to say all sorted, I can come and collect my car. Low and behold all is fine until last September when the cubbyhole broke again and now the seats were squeaking and the back windows are STILL slipping. This is ridiculous!!!!! I go back to Ford the service manager says they will call me to set up a time to bring my car in and they will give me a loan car and sort it all out. Have you heard from them, because I have not. A year has passed and all I have had is problem after problem.. I never paid peanuts for this vehicle I expect something decent, or is that too much to ask from Ford.. Your after sale service is disgusting....
