Blocked line

I had an issue with MTN for change of dates of my debit order. This is though even though I had communicated with them, they blocked my line. Upon conversing with a gentleman who assured me that they had fixed the problem, i was still unable to call. I gave it till the next debit order date but even up until now, I still cannot make any calls, even to the call centre number 808. I sent an email to have the issue fixed and was given the reference number #*** and informed this complaint will be looked in within 8 working hours, I am still 3 days later waiting on any form of response from MTN which i have not received.<br> <br> I do not even know what to do now as even the calls to MTN (808) are blocked and am unable to communicate with anyone about this.<br> <br> This is terrible and extremely disappointing as I have been an MTN customer for well over 4 years but my loyalty is seriously being tested.<br> <br> Mark
