Disgusting service from Call centre agent

Phoned DSTV and spoke to Renita, explained to her the issue I have been having with my account. I been with DStv from 2015 but now this issue of no debit order going off my bouquets being changed. Renita advised to pay the amount and it should be sorted out and she will escalate the problem further about why my debit order details cannot be verified. After talking to her she forgets to put the phone down and talks to her colleague in the background talking ill and laughing at me as I was so irate about my account. IS THIS THE WAY YOU TREAT YOUR CUSTOMERS AND IS THIS THE EMPLOYEES YOU EMPLOY TO TREAT YOUR CUSTOMERS IN THIS MANNER..Would be nice if she at least put the phone down so I could not hear her. But I did,....I want an apology from this woman...I did speak to her after the incident and told her I will report her and she could not speak.....Multichoice you need to come back to me regarding my Account and the apology from this woman.
