Disrespect, rudeness and arrogance

I am a regular customer of Superbalist/Takealot and I collect and return my items from Fontainebleau depot. Today was the worst experience I have ever had at any store. Firstly, when we got there, the gate was not properly open making it difficult for vehicles to enter and leave. Secondly, when I got to the office, there was a queue, which I found out was because of a totally *********** young man who did not know what he is doing. Thirdly, when I got to the front of the queue I informed the young man that I had 1 return and 2 collections. I told him that we will process the return first and then the collections. I have processed many returns at Takealot with competent staff, but this was a nightmare on another level, the young man did not know how to do the return so he went off to call for assistance. He returned and said that we have to do the collections first as the lady who could help would come "just now'. I told him that that was unacceptable and that he should call the lady now. He subsequently called Rebecca, who TOLD me that I do not know what I am doing, and that she is TELLING me how it MUST be done. I completely shocked at her level of rudeness and arrogance, I told her that I would send an email to her boss about her terrible behaviour and she said "DO IT, I DON"T CARE" Takealot staff are insulated from complaints because they are an online business, so nothing is done to rude staff members.
