Poor Service

Since 12/8 I have been emailing and phoning Multichoice call centre to allocate my payment. I have been using the same banking details for the past 2 years and payments made in September and Oct reflect on their system. However since 12/8 my DSTV has been disconnected every week without fail and each time I have to call to reconnect. Every call centre agent tells me the same thing which is that the payment has not been allocated and it is done by a different department so they cannot help. They promise to reconnect me and log a case number to get it sorted out. I even spoke to supervisors who assure me it is sorted. To date still nothing has been done and I am really frustrated now and ask for your help.
