No customer service at MTN Brooklyn

The staff at this branch admitted that they did not know that the advice they had given me about the carry over of airtime from one contract to another was wrong. They logged queries yesterday 7 May15, but was still not answered today 8 May15. Phoned 808 myself and found out from a call desk operator Ms Lillian Hoko that this airtime will be effective only after my minutes are used up for the month. Thank you to this lady who knows what is going on and also logging another call for the next issue. Thank you Lillian! <br> I also tried to upgrade my wife's contract yesterday, but this was also unsuccessful. On the MTN system I am registered as a corporate client and the system would not let the operator process with the upgrade. I am not a corporate client and receive no discount! Queries were logged yesterday and today, but still no resolution. The staff member Ms C du Plessis is not competent and showed a lack of commitment. The manager also tried but used the excuse that there was a problem with the amount of lines and connectivity. I tried to phone the branch this afternoon 4 times on all their numbers, but no one answers the calls! Is there anyone at MTN who knows how I can upgrade!
