Useless MTN Customer care

MTN phoned me in regards to a new contract. Which I have agreed upon. They took all my details and said we can expect delivery to take place between 3 - 5 working days and that a courier company will come in contact with us in regards to delivery. Its been almost a week now that I have continuously emailed and phoned MTN just to be transferred to another consultant that puts me on hold for 30 minutes. MTN's customer care is useless and pathetic and I am amazed that they still run their company with such *********** people. Why are you in customer care if you cannot assist a customer with a query? I still have not received anything. The only feedback I received was when I had to call them to ask them what is taking so long for delivery - the only answer they had was "oh there is a delay with the courier company due to them taking stock ", and then she gave me a number to call if we don't hear anything within 48 hours- I currently work at a courier company and there is no such thing as taking stock! its as easy as picking up and delivering. I have not yet even began my contract with them and I already want to cancel it. Poor responses and poor employees.
