Telkom is impossible to contact. Appalling service.

I've been trying to contact Telkom for 3 weeks. How can it not be possible to get a phone company on the phone?

Telkom said that I missed a payment, but they didn't deduct any money from my bank account. And now they want to charge me for a missed payment. On top of that, I asked them to close my account (online) and I've not had a response.

I'm currently overseas, and it seems that Telkom doesn't have a normal phone number starting with the SA dialling code 0027, and the free phone numbers can't be called from outside of SA. Their online chat service doesn't work, and no one responds to emails or requests to call me.

All my issues could be resolved in a few minutes, if only someone would respond. I've spent hours of time over the past 3 weeks trying to contact Telkom, and it is literally impossible??!!
