Telkom Contract ****

I have an existing contract with Telkom. Two phones and a router. I received a text on Friday notifying me that I am owing an amount of R1402.95. When I called to enquire, the recording for self service confirmed that the same amount of R1402.95 was paid on the 30th of April 2019. When i spoke to the consultant, I was advised that I only needed to pay R24 and I paid R30 just to be on the safe side, I am still not sure why I was asked to pay that amount. I thought the matter has been resolved until i received the same text today (Saturday the 12th). No one is able to assist regarding this matter and I keep on being told different reasons. Today I was told that Telkom personnel did not update my baking/ debit order details hence there was a delay in my debit order and I have to pay this R1402.95. The question is that what is this R1402.95 for and why should I pay for something that is absolutely not my fault. The confusing part is that I recently took out a router and I would not have been able to do so should my account was in arrears.

I am looking forward to getting feedback regarding this matter.
