Cancellation is a headache

I have a business account with Telkom and i cancelled the service following the procedure as per telkom's request.However, after multiple requests, the cancellation hasn't gone through.This is ****************,i don't use the service and keep getting charged for it monthly. Since June to date, i have been charged monthly after multiple requests to cancel the service. I am really disappointed that a company of this stature behaves in this manner.
