Absolutely disgusting and *******

I have been with Cell C since 2015. Never had problems, always helpful...last year October I cancellled my contract. Phoned in, gave my notice. Everything went smooth. Then in December they started deducted ludicrous amounts from my bank account- I would phone the bank, reverse the transactions and try and get hold of them. I have been doing this mobthly since then because when I block their debit order(which isnt approved) they use a different referance number. No one is helping me, I am still waiting for the manager to phone since Friday 2 weeks ago(after threatening with legal action, which I will now be taking). No one returns my calls, no one responds to queries. I am literally begging for assistance....its **********.

I am struggling to understand how they have authority to still be taking money from my account. This is theft, they do not have permission. I am now following through with my last conversation with a very rude and unhelpful call centre lady- I will be using all other channels to get their attention.
