Upgrade messed up again

Once again MTN has stuffed up. I had an upgrade last year which ended up taking over 6 weeks to sort out. Once again I ordered my upgrade online. Last week, This week DSV deliver just the simcard. I waited two more days then called. The first operator informs me that I only ordered a simcard - which is R99 per month - yet MTN successfully have billed me for R499. I ordered Two phones. There is no record. Someone will call me back.... famous last words. Today again I call, this operator tells me there was a problem on the system but she can see I ordered two phones BUT I have to go through the entire upgrade process AGAIN, because there is an error on their system. ONCE again someone is calling back.... still waiting. I have been with MTN going on 7 years and their service is going down FAST. Two orders completely messed up within 6 months. I wonder how long this order is going to take?
