I hve a problem with MTN, regarding my contract, t month of May I went to MTN to enquire about upgrading t lady who assisted me by t name of Elizabeth told me tt they will hve to change from voice to data, and that? t progress will take 3 weeks. To my surprise tt took 3 days n my sim card was suspended. <br> <br> I went to the nearest MTN branch they explained to me into detail which the sales lady didn't.<br> <br> I went to t branch wher I enquired again t Elizabeth already upgraded my contact witout my concern, spoke to t supervisor, said Elizabeth was new so she doesn't know much... 17 may 2014 I took a laptop which again I didn't know about t sim card, as I was trying to use it.<br> <br> I called t customer care n explained my situation, was told to return t laptop, they must cancel t upgrade, which I did. The supervisor Thuso refused said I should come in monday bcoz ussd is not working. Monday he said to me there is no way I should return t laptop cause 7days has already passed n again his manager said that's impossible I can take him to court and change to vodacom.<br> From may till now I hve been paying R369 for something that I don't hve?. I only receive 1G monthly which I'm not using.<br>
