Bad service and ************

So I'm from sterns since there's this special trending I got there asked if the watches are still available they say no, I leave and try to search online I can't find it I go back to sterns to ask for their website she gives me an attitude saying you were here muc and I'm like yet you don't even hear what I'm asking she was like ask then so I ask for the website she says it's wwwsterns what what, I'm still puzzled about that she speaks to her colleague in Tsonga language and say they are just going to bore and bother us with these useless watches of theirs, so I'm like excuse me she says what I'm like repeat what you said she says I said the watches are finished and I'm like is that what you meant the colleague jumps in and he says yes and I'm like you know that I'm a Tsonga and I heard what she said the guy replies by eh ay I don't know then I told them don't do that and I leave the guy follows me and said hee what are you saying he starts to swear at me telling me that he'll beat me. Is this how you treat customers
