Vodacom Terrible customer service

I prematurely paid up my contracts and requested to be changed to pre paid. This was done 2 months ago and has STILL not been processed. Vodacom is still charging me the monthly contract fee!!!

I have called the call Centre about 20 times(just get put on hold) and gone into the Vodacom store numerous times (where Im told they are taking this up with the call centre)and this will be escalated.

Nothing is getting processed and even though I paid up the contract I have been charged R1000 in December and in January.

This needs to be refunded as I'm paying for something I've already paid for.
