Bad service from vodacom cancellations department

Last monthsI called Vodacom to put a cancellation request on two of three of my contracts ***. I was sent premature cancellation forms with outstanding amounts to sign and send over with a copy of my id and proof of payment (which i did do)During the 1st of September I checked the balance on my number and it showed that minutes and sms's had been allocated. I called Vodacom to check what was going on and the guy I spoke to said that he could see that I had called to cancel my contract and that he would put through an immediate request for a cancellation and ask them to reverse any billing for September. When I asked for a reference number, he told me that I would get an sms. To date i have not received an sms. I called in yesterday again (08/09/2020), The consultant I spoke to said he would personally handle my matter and make sure that it got solved . I still have not received a call from Vodacom, but I did get a bill, which includes billing for the contract I asked to be cancelled. I have been a loyal Vodacom Contract Customer since 2016,their cancellation department and process is Distasteful and and disappointing and im thinking of canceling all the contracts i have with them and go to Telkom
