Pathetic service

I have 2 mondo telkom contracts. I am at my wits end. I e mailed my proof of payments to telkom. They debited my account 2 days later. I called 10210. I emailed. I've spent 2 weeks trying to resolve this. I mailed the ombudsman no answer. I e mailed the director General of telkom. No answer. They do not have any other platform to lodge grievances and yet the call centre does nothing to resolve complaints. The staff tell you directly. No managers available and no e mail addresses. You must call in to complain and they escalate it. That does not happen. I wanna cancel both contracts. I'm fed up of such incompetence.
