FAULTY TABLET

I bought a TABLET last year around August 5 days after I purchased it ,it was giving problems charging I then took it back to the store when I got there they charged it and it was working.A week after it gave the same problem I took it back because it was switching off while chatting on it.They said no all of these kind of machines does that so I should not worry it will eventually come right.<br> <br> I left and after a day or 2 it worked again.Now the third time it decided bot to charge again sometime this year.I went back to the store they took it and promised to call me again they never called me I had to go fetch it and they gave me saying it is working.Now when I got home it was not charging again and I took it back.It was with them for about 3 weeks they never contacted me saying a single word as their customer.<br> <br> I went there again last week Wednesday and I was told to return on Thursday to fetch it, it is done....when I got there the person who helped me told I need to change the battery of the tablet.Now I asked them to change the battery because it is clearly that when I bought it ,it had the battery issue now they are saying they do not repair batteries but my issue.
