Unacceptable bad service

I received a message from Mr Price that my credit has increased to R3300 .When i arrived at Daveyton Mall ,I went staright to Mr Price Cellur or Mobile ,Mr Price that sells phones and laptops ,and related products.Then a very nice lady inbthe morning around 11:00 am assisted me ,i then explained to the lady that I will come back after work ,but when I get to the office in Daveyton I then changed my mind to fo back to Mr Price Cellular or Mobile to use my credit to buy a laptop .I found a different lady by the counter she assisted very well ,but she had to call the call centre to verify my account .Suddenly I was assisted by a certain lady again by the name of Nokuthula at Mr Price credit department ,she asked questions I answered very well and some of the details she updated them such as ,Daveyton is in the East Rand and so on .I produced my ID card first ,as I have opened my account with my ID ,then I produced my license but it was not asked by her "Nokuthula" .I produced my expired license just incase they dnt trust me .Suddenly my expired license is an issue .I explained to Nokuthula that the first point of contact is ID card and not license ,license can be used as a secondary document should I dnt produce my ID card .But she was difficult telling me that my license has expired, and I am telling her that my expired license has nothing to do with my account ,I opened my account with ID card .Then I said to her that I will report this to hello Peter and with bad attitude, she said "you can go ahead " the reference of the call is 6929936 and email address she said I can complain is ,service@mpt.com .So in a nutshell ,I would say that ,Mr Price must hire people that are competent ,if I was a white person ,I would be assisted. Hello Peter please attend to this matter ,if this is not solved ,I am taking this to the competition Commission so assist me further .Regards Itumeleng Kekana
