Bad service

<p>For the past couple of months i have been owing MTN for something no one can explain it to me, i use to pay MTN R700 per month, my account was in credit every month, Then i reduced my instalment to R400 because they declined an added contract, that’s when SH#T it the fan, all of a sudden my account was from R400 up to R900 per month which no one could explain to me, the ********** 229 number i have was a 24month contract for +-R220 per month, the amount changed to R359. who changed it i have no idea, called the call centre numerous times no one could explain the hike in my phone account bill, went to MTN store in The Glen 3months ago, where the lady logged a call for me as someone at the back office needed to investigate why my account is from R400-R900 till this day no one has called me, i paid R400 on the 21st and 22nd i received an SMS overdue account R560.80 i have no idea what this money is for, i buy data the date expires after 2days, i spend more money on data than anything else, it seems like I’m paying for someone @ MTN's data bundles, i would like to have a breakdown of all the data i used and what I’m paying for as this is reductions- i will take this up with the Ombudsman as its getting out of hand now, the fact that no one can explain to me what going on ****es me more off..</p> <p> </p> <p> </p>
