Pathetic customer service

On 26 January 2018 I bought 2 bed linens at Boardmans Mall of Africa, when I get home unpack them to my surprise both linens were dirty and 1 was even teared. Following day I went to Boardmans Lifestyle mall as it is closer to me, as this lady was assisting me I asked if they take things from display dirty as they are pack them and sell back to customers, the lady said I should have gone to Mall Africa and ask them that. I asked for the Manager she said Manager is not in, I asked for whoever is standing in for the manager she called this other guy who also told me to go to Mall of Africa and ask them as they do not know how things are done there and the guy left after that. I was so furious I told the lady that all I wanted was an apology from them not that kind of attitude, to me they present Boardmans it does not matter which Boardmans I bought items from if I return them because am not satisfied whoever is assisting me should apologise on behalf of other branch not give me attitude. I asked for her name she just left me there, then that guy standing in as manager came so full of himself I asked him to write down his and her name. They were so rude both of them Boardmans should take their staff for customer service courses, we do not need that kind of attitude when being served. They are there to serve, that is what they app**** for to serve Boardmans customers.
