Terrible Service/******

I was contacted by MTN to do an upgrade on my existing account. I have a mobile contact with them and opted to upgrade the package to one of their laptop deals they were running at that point in time. I spoke to a consultant they did everything over the phone. I STILL have not received the device, they said that would be sent to me by courier. I have called, emailed and was sent from one department to another, spoken to numerous consultants but all for nothing as the matter still has not been resolved. But of course they have been charging me for the upgrade since then!! AGAIN - what are they charging for if i still have not received anything?? MTN was not helpful at ALL, i mean why would they be because they were getting their money. I got sick and tired of calling and complaining and being sent from one department to the next with no luck so i decided to stop the debit order. AND guess what, now they can call me back and threaten to have me blacklisted! MTN you are a bunch of ******!! Charging your customers when they have not even received a device that was supposed to be sent almost a year ago!! FIX YOUR MESS!!
