Bad Service

I made double payment on acc ***0 in error intending to pay a different acc ***2. I was so unhappy with the service I received from the agent Justin at the Durban call center. Who refused to assist me telling me it cannot be done I requested to be transferred to someone senior which he did not, and I also requested to be called back as I was running out of airtime he did not bother to do that either. I feel so discriminated because I'm female and black. He didn't take my issue serious, only it was another race this would have been sorted with no issue. Multichoice please address this issue and I want my line ***2 to be open before the end of the day.
