my tablet

My husband and i bought samsung tablets last year september the tab 4. After a few weeks my tab started giving problems i sent it in after 2 months i got it back and it still didnt work. I went to take it back to send in again but the store had closed down. Now im been told to take it to pretoria if i want it fixed. I was talking to someone at head office he said he would call back and still hasnt. I dont see why someone wants to givr service then makes getting something that you paid for your problem. If it was a contract and i missed one payment they would be all over it. But now that its cash they dont wanna give service. I dont understand this. This is outrages.<br>
