Pathetic Vodacom call centre agents

I contacted Vodacom cancellation dept on the 13th Jan 2021 to cancel 2 contracts that ended in december. The Vodacom call centre agent did not process the cancellation and was very rude when I asked for a refence number for the call she refused to give me one stated that one will be smsed to me, which she never did. In February I was called by Vodacom again advising me that I had 2upgrades due. I informed the consultant that I had cancelled the two contracts to my disbelief it was not been done so the consult tried to help, but she also ****. In March i contacted vodacom yett again was promised that they Will follow up and get back to me yett again lies, lies and more lies. Eventually after 8 frustrating phone calls i did manage to speak to a consultant on the 20th of april and she was very helpful and did cancel it for me. When I queried why the original cancellation requested on the 13th Jan 2021 was not processed I was told that they would have to investigate the matter listen to voice notes from their call centres and than need to decide if they will credit me!!! In that time from feb, march,april I have been paying for somebody else's mistake. I have been dealing with Vodacom for the past 16years and I am disgusted and disappointed with the pathetic service. Its amazing how efficient vodacom is when it comes to upgrading and new contracts but they fail to help clients when it comes to cancellations. I think call centre agents need to be reprimanded for false promises and rude behaviours!!!
