bad service all the time

I been visiting Ackermans kwamnyandu for some time now and I always experience this bad customer service from the cashier. This cashier who is name is Sanele always call me maka Ntsu which is the product that is used by girls for wrong reasons, the only thing that make me angry is this is my first precious son and my husband is really love my unborn son. Sanele always call customers names and the other day I ask for se help in pre boys department the respond that I get from his was so bad he didn't even tell me nicer he was so rude and tell me he does know about that stock and he say I need to look for myself course he's busy with something but the only thing he was doing was chatting with other cashier and one customer that was helping by other cashier. This is not the first time he's this arrogant towards customers we've been complaining to the manager Nana and she's not doing anything and I had other customers say that they're in a relationship. what kind of a manager who date staff member. that why he behaves like this , we are customers we deserves to be treat right , he needs to be teached about customer service. I'll rather go to megacity then Ackermans kwamnyandu umlazi
