Telkom sharing personal details with ****mers

Unresolved dispute going on for 2 years now, cancelled my internet and telkom did not cancel and stated i owe them 2 months internet charges. They then shared my account details and cell no with Nudebt who has been harrassing me through sms only for over 2 years. I do not even live in South Africa anymore but the sms keep on coming. No correspondance through email, just sharing my personal details with ****mers. For sure against the law and a dirty trick. Telkom if you something to say email me, do not share my details with ****mers, you are supposed to abide by SA law but seems you do not know where to draw the line.
