Vodacom Fibre and Cellphone call centre poor service

I requested cancellation of my Vodacom cellphone contracts in December 2023 via Vodacom call centre 082135. In January 2024 after receiving the statements i realised that it was never cancelled therefore i had to pay for two months extra where the contract was canceled. These contracts was utilised by my kids. Unfortunately due to there bad service in not cancelling the cellphone contracts i fell in arrears and during April 2024 my fibre account was suspended. Now i must pay for April 2024 and i never received any service's from them. They increase the amount of my fibre from R799 to R849 without even getting approval from me if i am interested in this upgrade. I didn't have any contract with them and haven't sign any documentation with them now they say i must cancel within 30 days. Now i must pay R850 for Vodacom for nothing Mahala bad service and there agents cannot assist you where you come to a point where you are getting tired of being transferred from one person to the other then the call is dropped. Now i wonder if i will receive the minutes and data for the months that the phones was blocked from there network.
