Incorrect Billing

On 10/02/2016 I received my billing invoice in an sms. The billing amount was incorrect ( R783.39) when it should have been R101.50. <br> <br> I called the queries line of which I was told that the billing was infact incorrect and that even though I have notified them before the amount is debited from my account the amount will still go of at a later date (Andy Myaka was the person I spoke to). To date I have not heard anything from Telkom resolving my issues. <br> <br> Today 19/02/2016, I had to call the centre to enquire about my refund. Why is it that Telkom can get paid on time but when it is a fault on their side consumers need to wait days for them to receive their money back. Who has R600 to just throw around? <br> <br> My case number is ***9.
