Faulty tab - pathetic service

On the 25th July this year, I took my son's lenovo tab to the mtn store at the glen shopping centre. He'd only had it for a few months then it died. Since then the only time we received feedback was when we went to enquire at the store. We have heard all sorts of excuses from lenovo not being supported by mtn(but they do sell it) to a change of management at the store. The strangest this is that my axcount gets debited every month like clockwork. <br> <br> I got this tab for my sone because he needs it for hos university studies. It hasbeen over two months and still, no phone call, email or snail mail. I am extremely angry and disappointed since I am a long time cient. I have never received such uncaring, poor and PATHETIC service from anyone before! I am considering canceling the contract and possibly taking legal action.
