Poor customer experience

I went to protea gardens dstv store to report the satellite which fell due to wrong installtion, and a lady by the Nonhlanhla after reporting the incident gave me a terrifying service of which i felt very small insuch a way she told me that she cant help me because i didnt bought from her i bought from her colleague pretty.I couldn't believe the customer experience i received,i had to go fetch the lady who assistant me after asking for her number and the poor lady had to agree to come through so that she can be able to assist me.I believe that my fellow african need to get a proper customer service lessons if not i pity thta branch will lose their customer due to her way of talking to the customer..Thanks for Pretty and Mzwakhe who came to the rescue and willing to go extra miles just to help me out keep it up not for me but also for your future customer who might come through with the same problem as i.
