Bad customer service

I was at PEP Hatfield this morning to get my tissue oil as usual (I work in the center & I was on tea break) I stood on a line which only had 2 people while 4 employees were around the till, 2 of them were helping 1 customer, one of them asked the other to help us (customers) the other one called Zanele refused and said “this is not a line” in seTswana. I finally got to the till and raised my grievances and the one PEP employee with no name tag quickly said “are we doing nothing” rudely in seTswana. We argued about me not being assisted and I told her I’m gonna report the service and she said go ahead. As a customer and an employee of the center I understand the COVID-19 situations but for 4 employees to be around the till and not assist is is absolutely unacceptable.
