Bad service affecting my credit record

I opened a vodacom contract about a year ago and signed for a monthly debit order to take place. At the end of the month I received notifications asking me to pay my bill. I went into Campus square multiple times, 3 times to go over my banking details and ask inquire about the debit order that wasn't happening. Since, I have had 4 phone calls come my way inquiring about my unpaid bill. I have given my banking details to the vodacom customer line and with no success as yet. <br> <br> I am now in Hong Kong and am still receiving messages inquiring about my unpaid bill. Why is this not coming off as a debit order when I have inquired and corrected information several times.<br> <br> This is negatively impacting my credit record and I am disappointed in the poor quality of service that I have received. I cannot and will not come in every month to pay my account. It must come off as a debit order as requested on too many occasions.<br> <br> I am shocked and want this resolved right away.
