Poor communucation.

Called ATD Pretoria several times today for an assistance with the debit order, firstly the debit order amount was increased and an additional amount for the radio was added on December debit order, without informing us and which resulted to the debit order being bounced and we were charged unpaid fee by the bank, after calling ADT several times yesterday and today to sort out the issue, we were told Portia from finance department will contact us, but we haven't received her call, we also tried calling today and we were advised that an email has been sent to Portia to call us back but still we haven't been called and this is frustrating us as we are going to Limpopo, the reason for the call was to arrange with ADT to re debit the account to avoid problems during this festive season.
