pathetic customer service

Went to Cell C store at Midlands mall this afternoon, servcie was unprofessional, arrorgant, rude and pathetic. A lady by the name of Racelle was assisting me re: my account, whoilst helping ,me a lady from the back bring the phone to her to talk. How can they do that without 1. apologising or asking me permision if they can take a call. She goes on talking which seems a personal call. I ask are you not going to assist me and she just told mew call is from head office and walked to the back behind the doors. A Black lady from the back came to the front and asked her am I not getting the help was aslo ignored and just told call was from head office. The l;ady name was Precious who is a supervisor and did not bother to assist me. Wen Precious went to the back Racelle came to the front and started shouting at me abruptly and abusively and told me I can go to social media and complain. I was just left there standing no one assisting me. After the indian lady finished with her customer she assisted me out. Service standars at the mall branch hes declined to where there is no customer care. some of these staff just at times walk out when it is quiet outside their break times. Also more personal conversations take place. I work oin a customer service environment and know what is customer service. I will rate the service as 1/10 Please investoigate
