Samsung Tablet T2111

I have the above table on contract at MTN I have been having problems with the tablet now for awhile, have been sending it in for repairs but it has been the same problem every time, it start getting hot freezes does nothing and switches off, it will come on after awhile and it will work fine, I have send the tablet in for the 4th time now same problem only now it is completely dead the screen does not even come on, I get told that I load too much data on the tablet I am so sick and tired of this story. i have been sending e-mails to the repair centre manager as well as to customer care till today i have received no reply on my e-mail nor a phone call, i need this sorted out a.s.a.p. i am not very happy with the service of MTN and i am not the only one a lot of people are complaining about the poor service.<br> <br> i really hope somebody will respond to this.<br> Anna-Marie - 011 ***
