ONE OF THE WORST NETWORK PROVIDERS!

Telkom must be one of the worst network providers. I took a 2 yr contract with them which recently ended in March but they continue to bill me. I was asked to call a month jn advance to cancel my contract which I did, then I was asked to make payments 10 days before my debit date cause I wanted to clear my balance. I couldn't withing the 10 days or before my debit date but I made the additional payment which they billed me an extra R100 or so clearing my outstanding balance for ending my contract. I was told all is hood and my number would now be prepaid, I even got extra data for being their customer. Only to get a bill for an unknown amount of R286.43 yet I've settled my balance. Tried calling their customer support where i was bounced from department to department, then got sent a WhatsApp link which is useless when you a frustrated customer seeking immediate assistance and clarification. I must have emailed all the email adds on their site and the ones recommended with no avail. I'm tired and will jo be paying them a dime!!!
