Bad customer service

I experienced bad service from a store teller in Ackermans at Mall of the south , her name is Nomfundo What irritated me initially is that the queue was long however there were only 2 people assisting a long line . I finally get to Nomfundo she's not polite we ask her a few questions and whenever she has to answer she looks like I'm holding a gun to her head and doesn't want to answer alright I see that she isn't in a mood I stop talking to her no problem

I took a lot of clothes so she tells me that my card needs authorization and she has to go get a phone to call ... She disappears for about 20 mins and we still need to call for the authorization. I'm thinking the entire time she's not there she's sorting this out ( mind you the line is getting longer and it's just getting hotter in the store ) She gets back with her attitude no explanation or apology for disappearing for such a long time . She makes the call and she's just irritated the entire time make sounds showing us how irritated she is

I get that it's festive and maybe she's assisted a lot of clients during the day but that's not the clients problem all She needs to do Is to be polite and civil to clients only

I'm not Happy with Nomfundos customer service there is no smile from her , obvious irritation on her face like she didn't want to be there . No Nomfundo you can do better dear
