No feedback

I went to capitec The glen on Monday 4May to change my debit order date for a loan I have with them, as I have changed jobs and my pay date has changed. I have since had no answer from this branch to let me know what is happening, and when I phone the call centre they advise me that nothing has been changed yet......I provided all the paperwork that was required by me. when I phone the branch I cannot get through....<br> Why have I not had any feedback!!!???<br>
