No response from Vodacom cancellations on my previous Hellopeter review

I have tried to cancel the number *** at Vodacom Cancellations since Feb 2020. In Feb they told me it was too early, I must phone in March. Then I phoned in March, and they still said it was too early. Then I phoned the Accounts department, and they said I CAN cancel it in March, so I phoned the Cancellations dept again in March. The guy said he can't cancel but he will make a note for 1 April. Then in April, I decided that I don't think this guy is going to read his note, so I phoned Cancellations AGAIN to cancel. They confirmed that end April I will pay my LAST payment. And then, in May, I still got the amount of R339 on my account!! Today I phoned Accounts again, they said Cancellations DID NOT CANCEL the contract. I also sent an email query earlier this week, but NO REPLY after giving my ID, account number and bank details. So I decided I am not going to spend ANY more time on this, trying to phone everywhere. Vodacom, please cancel contract number *** from April and deduct the R339 from my May account!!!! If there is any doubt, please go and listen to the recordings before you phone me. Let me know urgently!!!!
