Poor service

MTN has time and again proven to me that it does not care for their customers or the service they provide. On Sunday night I called to report to this so called 'service provider' that my data was depleting abnormally. I was given a reference number for this call and told to wait for 48hours. I went on their twitter page and saw other people complaining of the same issue. Last night I called to follow up on my query and the consultant told me that the issue was resolved and seeing as the fault was on their side they would reimburse my data but this too would take another 48hours. I loaded data and the same thing happened. Upon calling the call centre back amd explaining the situation to them AGAIN I was told that what the previous consultant had told me was not true and that the issues is actually my fault and not theirs. Funny thing is how is it that 4 different people had the same issue on the same day yet MTN tells us its not their fault. When it comes to them demanding you pay your monthly contract fee they want it immediately but drag their feet when you demand the service you pay for. This has happened twice before (December last year and beginning of March this year). Yet if I do not pay they do not waste time in disconnecting my service. I want MTN to reimburse me for the data used and the fact that they are ***********. You do not care for your customers. Need I remind you that my phone does not run on oxygen but I need to spend money to recharge on top of what Im already paying monthly.
