Abused by callcentre agent

I called in this morning, 8/06/2015 to inform the accounts department that payment was made via eft on Saturday 6/06/2015. I then received a call form Nontobeko - a callcentre agent who says that my account was in arrears. I explained that the EFT was made and she insisted my account was still in arrears. I asked if there was any way that she could expedite the payment as i i would like to make a purchase, she bluntly refused. She was extremely rude and barely gave me a chance to speak, i had to constantly interrupt her to get a word in. I then asked for her supervisor - I waited and she got back on the line saying that they will phone me. I asked for her Name which she provided and refused to give me her surname, then i asked for her supervisors Name which she provided PRICILLA RHODES. I asked for reference number she said they use the account number. when i asked for her surname again and her supervisors email - she then says that she has given me too much info and threatened to cut the call. This is unacceptable - we as clients deserve to be treated with respect and not abused. People like Nontobeka needs a lesson in customer service. without clients - Mr Price ceases to exist.
