Vodacom and their ********** transactions

I did an online upgrade with Vodacom. As per their terms I returned the handset and asked for the upgrade to be reversed as I wasn't happy with the handset. Several phone calls to follow up on the reversal to be eventually told I need to send an email. So .... I sent an email and amazingly enough got told the reversal of my upgrade had been done. Several more phone calls to confirm the contract would revert to the original contract and my upgrade would become available again! So far this is not the case. It has taken me 3 months to get the upgrade returned and reversed and yet my upgrade is still not available, my contract did not get reinstated to the same as before the upgrade and shock and horror I am still paying for a handset that was returned to vodacom in JANUARY!!! Why am I **********ly being charged for a handset I don't have and where the hell is my upgrade. Vodacom online is absolutely shocking and I will never deal with them again. Am strongly considering cancelling the 5 contracts I have with Vodacom!
