Behind on payments

Good day,<br> <br> Yesterday we received a call from Rochester Witbank, telling us that we are behind on our payments, but on our side the debit orders went off as we arranged with them at R 1 777 and some cents. We couldn't understand why they would say we are behind. The woman on the other then said that our payments should actually be R 1 900-00 and that is where we are behind and got rude. How can this be? On the agreement that we signed with Rochester it states the amount of R 1 777. <br> <br> Then to top it all off there is no manager to speak to and no way to get hold head office as all the lines ring for a few seconds and then the line dies.
