Cancellation of A Vodacom contract

Hello Peter I had a two year contract with Vodacom which expired last year December (2020). I called them serval times with an attempt to cancel the contract.

I called them few times again this year when they told me that my account is in arrears They then acknowledged that they saw my attempts to cancel the contract and they assured me that I won’t pay anything and that my contract will be cancelled.

To my surprise in February they deducted money again from my account R996.00 for the same account, I then reversed it. Today they suspended the lines to the number of that contract.

I don’t know what else to do since . Please Peter Please help

Thanking you in advance
