MTN USELESS AGAIN

My contract with MTN expired end July 2020 and due to the fact that their offers on phones were poor I considered cancelling. However I received a special on the app as follows: R139pm for 24 months keeping my current phone and receiving 150 minutes and 500Mb data per month which suited me fine. I went to my nearest MTN shop but they did nit have this special on their system and I had to contact customer services for this to be activated. Josh assisted me with this and everything seemed in order. This month I received the usual SMS to inform me that data and minutes were loaded BUT it was completely wrong. Contacting customer services nobody knew of this special and my package now consisted of 50 SMS's 50 minutes and 500Mb data at who knows R per month. They promised to investigate and return my call but nothing as usual. I sincerely regret that I again fell for their incompetance and no customer service at all.
