Annoyed disgusted disappointed

Hi, I have multiple contracts with vodacom, 2 of them ended on the 19th of October 2020, I called vodacom on the 6th of October to cancel both the contracts, I have my call log to prove the phone call happened, but vodacom informs me there's no record of this. So my contracts were not canceled and I must now pay for another month. After complaining to vodacom this is the sms they sent me "Dear customer Kindly note that there is no previous cancellation request recorded on the system , which department did you call for your contract cancellation." so how do they explain my call log and why would I make up something like this? Shortly after this sms they sent me another
