Telkom Bad services, ********** billing

I have been trying to cancel my services with telkom from May, when they suspended my line. But they still are billing every month, and when I try to cancel it online, it just states that it has been suspended but yet they keep on billing me. My complaint is that how do they keep on billing me on the services that i'm not even getting in any case this was not even a contract it was a month to month services. I must say I regret the day I took telkom services. This is ***** because even when I call their call center for assistance they also cannot assist me. I truly don't know what else I should do, but what I know is that I will not pay for something that I'm not even using.
