Pathetic Accounting

Pathetic accounting. My account is fully paid and yet Telkom tells me I owe them some R1238 (which I categorically reject) and cuts my service. You can't even phone Telkom 10120 if your line is blocked so have to use Chat line, who confirm that I have no outstanding debt but that I must wait for feedback (they can't tell me by when) before my line can be re-instated. Their new wireless landline service is unreliable or not clear or both, so I'd guess the time has come to cancel after being a customer for 42 years.
