Disgraceful service

The lack of service I have received from Vodacom is atrocious! I have been calling since December 2020 to cancel my contract and every agent I spoke to promised me it was done. Your cancellation's department might as well be closed! Every agent I spoke to **** to me, instead of moving me back to pre-pay I am stuck on a data contract that I no longer need. My charges for the contact have increased because the discount has ended. My request is very simple, CANCEL MY CONTRACT AND MOVE MY NUMBER TO PREPAY! I cannot see how this is too much to ask, it's not like I'm leaving the network! I have received multiple references for this issue and till today no one at Vodacom has called me back. I want my contract cancelled, my bill recalculated, and my money refunded for all the extra charges, I refuse to be held financially responsible for your *********** retentions team. Please listen to all my previous calls and deal with these agents they are giving Vodacom a bad name.
