Refund still outstanding - Bad Service

I wrote a report on Hello Peter late last week complaining about an Agent by the name of Thabo being very rude to my son Ruan Moller, and was of no help. Late the same day I got a call from an Afrikaans speaking lady apologising on behalf of MTN stating she would sort out the matter, and that MTN will refund my son by Friday, latest Monday 11th of January 2016. To date no refund was made. I tried calling MTN on ***, the same number we called last week to try and find out why the refund has not been made yet. The lady that assisted me today advised that Alice vd Merwe from Complaints Department was the person that assisted us and that she was going to send her an email again, trying to find out why the refund has not been made yet.<br> The lady assisted me today was Ability Mojana, she was very friendly and helpfull.
