MTN's deafening silence

On Monday MTN claim to have loaded my new bundle - ever since this happened, I have zero access to my data. I cannot access Whatsapp, go into the Internet or go into the app store. As I had received a message a few days before (after midnight, which runs against the law and was woken up) to say I had exhausted my bundle but did not need to reload as I could connect via WiFi I decided not to buy more data prior to the bundle being refreshed. I logged the matter when after a few hours after receiving notification that everything had been loaded and I could not access and this has fallen on deaf ears. They sent a reference number and then asked for info, which I provided, but since then the silence has been deafening. They simply could not care. I have had foreign visitors needing access to my employers premises and could not get the Whatsapp - we then have had a two-day workshop where we took everyone to a conference center in the country so they could experience SA but could not check in that they had been picked up or everything was in order - MTN simply could not careless. Three days later I still have no access and no news of what is going on - I am just expected to pay for getting nothing. Be warned this company is one who as long as they take your money could not care. I have been a client of theirs for around 28 years! It looks as though it is time to move.
