Account cancelled but billing continues ...

I had a Cell C fibre contract. On 28th November I emailed ********** to cancel to contract, since I was emigrating at end of December 2017. I received a reply the next day, 29th November, saying that the cancellation was noted and scheduled for 31 December.

On 8th January 2018 I received an invoice from Cell C for the fibre connection, payable at end January, for the month of February. I decided to check my bank account, and noted that I had been debited at end of December for January 2018! Clearly the account was NOT cancelled as requested.

I email again, and received a reply to the effect that the contract will be cancelled at end January! This is NOT what I asked for. I am no longer in the country, I have no need for a further month. I app**** for the cancellation timeously (28th November), and I fully expected the cancellation to take place as promised.

I require now that (1) the account is cancelled forthwith (not end January), and that the R1,000 you took from my account for January 2018 is paid back.

Thank you
