Still debit my account!!!!!! 4 months later

After I gave you 3 months notice of my cancellation at the beginning of May this year you still proceed to debit my account for the full amount every month since!! I didnt even have a signed contract with you!!<br> <br> I have now moved to the UK and see that you continue to charge me for something that should have been cancelled months ago!! The chances of me contacting anyone from telkom from over here are absolutely ZERO just because I know of the incompetence that I will inevitably ended up speaking too!! Now what choices do I possibly have!! It amazes me that something as simple as cancelling an account can be that hard but then again we are talking about telkom....
