Dissapointment

3 weeks ago i went to truworths in west street durban to return a dress that was R650. Then a lady who was assisting me at the tills asked for a belt as the dress apparently came with the belt. I then explained that when i got the dress it did not have a belt. The lady reported the matter to the supervisor who was very rude en had such a bad attitude. She asked where is the belt en i explained again to her en she said thats impossible no staff would have given us the dress if it didnt have a belt and that staff member was supposed to write on the slip that there is no belt. She went on to say how are they suppose to sell this dress without a belt en i asked her wat must i do with a dress that does not fit me. She then instructed the lady to make a call and find out who was helping me that day and they said the lady was not there that day. I then suggested that they have a look at the cameras on that day and they will then see if the belt was not there en she just turned and said hhaybo those cameras are not working and she continued having a very bad attitude. I could tell that she was not interested in anything that i had to say and was not willing to help me. I was with my younger sister en we were so shocked at the way she spoke to us. Even if they were not gonna allow me to exchange the dress but there was no need for her to be rude or look down upon me like that. I was so angry and dissapointed at the way that lady treated and looked at me and as a result i said she can jst keep the dress because i also wont b able to use it. They gave me my receipt back and i left the dress wit them. Its so disappointing that a person can b so sure that her staff member will '' never'' make a mistake like that when i am an employee myself en i cant say i have never made a mistake at my workplace.
