Telkom *****s my money

I used to have a landline at telkom. Tried to cancel it twice, but debit orders are still going off. Now I also have another R999 monthly debit order firing at TELKOMMOBI#####. Someone is leeching off of my debit orders also. I am Blocking Telkom permanently at my bank. I have switched to other tellecomunications companies, I dont want anything to do with telkom ever again.
