Shocking service delivery

After 7 days of requesting a PREPAID SIM SWOP I had to insist on the matter being investigated!!! Not one of the staff I dealt with could even give me an answer as to WHY my sim swop was failing. I just got the same regurgitated responses... 'redo the sim swop' They did not even listen to the fact that I had already bought 2 starter packs and had them RICA'ed. Nor did the fact that I had been requesting this sim swop daily for 7days even strike anyone as odd?!?!?! Is this really the norm with MTN? I am disgusted at this kind of service!!!! It does not even bother any of them that this is the number I use for my banking and business - MTN has already cost me the potential business of 7days and now I get told that the investigation that I HAD TO REQUEST will take another 42hours!!!! Is this what MTN considers customer service?!?! All any of them did was try to get rid of me What exactly am I supposed to do to get actual service with this company????
