Annoyed

I'm highly disappointed with Telkom, I missed a payment one payment in June my line was suspended, the passed due amount was paid in July, but end of July Telkom debited twice the amount my line remained suspended I called many times with no luck. I managed to get gold of them and I was told I still owe R200 which was payed on that day my line was opened 3 days later. Yesterday I was supposed to pay 631 but they debited R1500 Telkom is the worst
