No feedback - Not fixing the problem

Took my daughters Samsung Galaxy Tablet in as it wasn't charging. They said it would take a day or so to fix. We never got any feedback from them and even the telephone number on their quote wasn't working. Needless to say my wife had to drive there everyday to find out what's happening. Everyday a different excuse. Eventually a week later they said that they got the parts and it will be fixed. We eventually got the tablet back a week later, We tried charging the tablet and it's still not charging (Original complaint). We took it back today and now suddenly they say that their contract with Samsung has expired and they no longer can do work for Samsung when a product is under warranty. I can see why Samsung why don't want to extend their contract as their work and feedback and customer care is TOTALLY pathetic.
