Upgrade nightmare

My phone broke last week and seeing that i can only upgrade next year Feb i decided to pay my contract in full and get a new upgrade. The following happened: 1 - Sat 11th paid my contract in full 2- Tue 14th Cell C confirmed payment was made and my contract is paid in full. Was told that within 24 hours i should be able to upgrade. 3 - Wed 15th i am asked again to forward proof of payment and told somebody would contact me, no one did. 4 - Thu 16th i was told again (3rd time) that they would escalate this and ring me back, i am still waiting. I have mailed POP to 3 different people and spoke to staff working in 4 different departments. My latest ref number is ********** 600. Can someone from Cell C please get back to me?
