Frustrated

I am tired of the shocking service I am currently getting from MTN, whenever I want to add an extra bundle of data onto my contract I have to call into the call centre and my call gets cut off at least 8/10 times before I am even able to speak to a person (please feel free to check my call logs to confirm this) and I have reported this on many occasions and not one person has contacted me back or done anything about this. Today's cherry on the cake is my new Data/ Airtime is meant to be loaded on my phone today and of course nothing has happened and when I call to get help I find that the call centre is closed due to unforeseen circumstances, how can strike action be unforeseen ? I am really fed up with the poor service that you offer! Perhaps it's time to look at another network, maybe even take advantage of those who offer free watssap service and up to 10k to buy you out of you contract ...
