Telkom is a ****mers

Around August or September this year, Telkom tried to debut my account for an old contract which I was willing to renew. They couldn't find any money and decided to stop the data SIM from working. Seeing that happen I decided to stop paying since they blocked the SIM anyway. But to my suprise Telkom keeps on increasing the money and debiting my account every month, which I of course dispute but I don't have any idea what they are debiting for. I think they are selfish ****mers who will do anything to reap off innocent people. If they were that good why did they block the SIM the moment I missed one payment after 5 years of being with them without missing a single payment? Telkom STOP it, stop messing with my account. I no longer want to do business with you. The worst part is no one knows how to get a hold of Telkom and they don't even have a complaint button on their website.
