Cell c Fibre to home

I have cancelled my fibre to home with Cell C on the 28th October 2020. I moved and they had no coverage in the area i moved too. I was advised by their customer care i need to cancel by existing contract. I did exactly as i was asked on the 28th October. . End of November by subscription was debited from my bank account again. I raised this with their customer care and i was advised they will look into the matter. Never received feedback. Eventually i received notification my subscription was cancelled on the 7th of December. However end of December my account was debited again. I raised another ticket on the 29th of December and to date i have not received my credit from Cell C. I will however report them on every social media platform and if i must i will go to their head office to get my money owed to me.
