***** on my account

I have a data line with MTN. On my last invoice I discovered that my amount changed. I followed it up with MTN and they confirmed that my account was *******ly upgraded. I faxed an affidavit to them, logged a complaint on their website and mailed their customer care. I did received feedback that they are looking into the issue. Since then I did send mails asking for feedback, and no reply from them.<br> <br> For such a big company I find it unprofessional and pathetic that a issue like this can't be solved nor feedback given to a client.<br> <br> I don't have access to my MTN profile and also no use of data. I need to work on the internet and are now blocked because of someone that can't do their work.<br> <br> MTN reference no: ***7
