the worst service topped by a very bad attitude

On Tuesday 13-10-15,i went into the store for an exchange,i arrived there at 16:15 and was assisted by mathapelo,unaware of the exchange process I gave her the slip and advised her I wanted a size bigger on both items I had,she told me the other did not have a bigger size and went to look for the second item,she has the slip in her hand as she was walking to the pay station then went to the back,she took forever to get back to me,by 16h30 or so another consultant came to assist me Gladys and told her to tell mathapelo I've been waiting to long so she should keep the size for me I'll come back the next day,Gladys went to the back,came back and with the pants a size bigger so I decided to go ahead with the exchange but the slip was nowhere to be found so was mathapelo,gladys called prudence to assist her and prudence said mathapelo is the manager and she's on lunch,she left me unattended,lost my slip and went to lunch,stood in that store till 18h00 for mathapelo to come back and tell me,she did not take the slip,i don't know how to speak English and if I want to view the camera footage I should follow the legal process which I'll find onlinel
