Telkom Mobile Billing Issues

Since we started our Telkom Mobile account for our business about 10 months ago, we have had 4 errors with billing. Each time the credit takes a number of weeks or even months to pass. Eventually we stopped our debit order with Telkom and then this month, we paid our cash due less the outstanding credit, and Telkom decided in their wisdom to reinstitute its debit order - they now have a credit that is outstanding for around 6 weeks overdue and they have taken the payment for this sum, plus received double payment on our actual amount due. This overbilling is obviously how Telkom manages to appease shareholders.
