Matter of Urgency - Unhappy Client - Poor Service!

I have called and sent emails to be assisted with a payment arrangement for my outstanding Vodacom account. I was initially assisted and requested for the debit date to be the last day of the month and since my salary date has changed hence I am requesting for the debit date to change. I have not received any feedback or any assistance. This company is so fast to assist with dishing out contracts but they lack customer service and do not know how to value their clients. I am available on *** or ***.
