I should have switched to Vodacom..

I've tried going through the channels, but once again I have to revert to MTN to solve a ridiculous issue. Reference number: *** So I upgraded online and I ordered the wrong phone by mistake. I contact MTN, they say no problem, I just have to reject the delivery when the courier calls to deliver the phone. I do that. Great. So when do I get my new phone? MTN says the courier company confirmed that they returned the phone but now they (MTN) have to confirm with their warehouse that they received the phone. This was a month ago. HOW LONG DOES IT TAKE TO PICK UP A PHONE AND CONFIRM THAT A PHONE WAS RETURNED???? And also, my contract has been upgraded to LESS minutes, LESS data, WITHOUT a new phone, but I'm still paying exactly the same amount. If I'm paying EXACTLY the same amount for an OLD contract and an OLD phone you OWE ME DATA and MINUTES!
