Bad Service

I got the most disgusting service at Ackermans Sammy marks..i was looking for a white dress for my child which i took the liberty of looking it up online to check availability and it was at Sammy marks,i literally showed the consultant the picture and gave them the SKU number but i was told to look for it the lady handling that department is on lunch i asked for a manger his name is Eunice which i doubt as they didn't even wear name tags he was very rude and condescending towards me infront of other clients proceeded to mock me by asking if i was ok and laughed looking at his phone and the sad part is even though the dress shows it's available in store he himself told me he can't find it since the lady in charge is on lunch..as someone who has experience in retail i know exactly what the procedure should have been..i intended on buying my child some clothes but couldn't even imagine giving my money to a store that has such disgusting service I'm really disappointed.
