ACPS ridiculous services rendered

I have been a customer of ACPS for the last two years or so. I have requested last year that my services are cancelled however i was still debited every month . I have spoken to the bank which informed me that ACPS as debt collectors are not doing anything hence i am requested to pay the full amount for my installments. I have then sent a second request late January and i was given confirmation that services have been terminated however R900 was debited from my bank account which is more than twice the amount i used to pay ACPS a month for their services. I try calling the number on their website and i have been told that the number has changed. I will not leave this here as i am being placed in a really bad position due to ACPS

i feel that this is putrid customer services as my position is not understood and without being consulted I was debited. I have sent emails and follow ups and i have been waiting for many days for an answer as one of the ladies assisting informed me that she will get back to me.

I want a refund from October 2017, I will not accept this.
