MTN Direct is very useless,i regret upgrading

I upgraded my phone on the 28th and i am still waiting for delivery. i was told it takes about 3 days and yet i am still waiting. i have had to keep calling because no one bothered to update me and each time i got the same response \we would check with zama what is going on, the phone has not been invoiced\" now how long can it take to invoice a phone? if you knew there was no stock why was i not told. i called again today and got the same response. MTN has become a very useless place. if i get no update in the next 2 days i will cancel this stupid contract how can i pay for a phone i don't even have? how can it take 5 days for invoicing a phone. you should close that stupid department all they do is inconvenience people.
