RIDICULOUS service from Vodacom RE cancelling of contract

I have to share my very disappointing experience with Vodacom. My contract was to end September 2020 and I have been calling them since August 2020 to ensure the contract is cancelled end of September 2020 and doesn't continue. I even went to the Vodacom store in Somerset Mall to ensure all is in order. Due to Covid I had lost my job so R800 a month isn't cheap. I was assured after each telephonic conversation that it had been noted the contract gets cancelled end of September 2020. Well Surprise Surprise, come end of September 2020 I got airtime and went to the store again to query this as the agreement was last payment due end of September but I wont receive airtime which was fine with me. Upon enquiring this, I was made aware that I had NEVER contacted Vodacom and therefore the contract was not cancelled. When I requested play backs of the calls as I had dates and times I was made aware that not all calls are recorded anymore. The lady which assisted me at Somerset Mall also had a stink attitude as she insisted I continue the contract for only R40 (or so) a month I told her I can't afford it which she responded, YOU CAN'T AFFORD A R40??!!! No!! If you ever get to read this, I can't afford a R40 at the moment. I was politely told that there's nothing they can do and the contract will now only be cancelled end of October 2020, another R800 which I tried to all extent to avoid as I cancelled on time as advised by the consultants which called me. Im sorry Vodacom. After being a customer for heaven knows how many years this left an unpleasant taste in my mouth
