MTN South Africa has the worst mobile support and upgrade experience of any telecoms company

MTN South Africa has the worst mobile support and upgrade experience of any telecoms company. It has now been 11days from when I started to inquire about my upgrade. I have been transferred to every department including the Customer Care Champions to retentions to the delivery department (dsv). In the whole process I was never contacted with any updates that forced me to phone MTN just to be routed around again. I will strongly recommend to stay clear of this company as they can not maintain customer records nor support contracts. They are quick to want to start a sale, but they do not follow through to finalize the admin.
