Cancelled but still debiting

Cancelled but still debiting

I previously raised this with hello Peter and apparently cell c advised that I'm not their client and I should address it with get more but I got to know about get more through cell c when I was their client. I cancelled my membership in may/june but to this date I'm still being debited but weirdly their system says my membership is cancelled when I ask them why do I receive messages that my membership bounced,they say it's a system error. When I ask why am I then debited every month if the system says my account is cancelled, they said they cannot advise on that as they don't know. Everytime my they debit I reverse it but honestly such is not life. I'm not getting any help from this and I'm getting tired of always reversing the.payment. I have attached proof of October's debit.
