Bad services from Jabulile and its not the 1st time

Jabulile store supervisor does not have customer service at all. And she is very disrespectful I was waiting on the que for 5 minutes ,waiting next on line then nexthing Jabulile calls her friend next to be assisted while im standing and it was my turn to be assisted . Then i asked what so special about that customer to just come in front of me without asking for my permission. I was told that Jabulile she is the supervisor , the store does what she says , she might be a supervisor but that shop doesn't belong to her she needs to respect all customers . She cant do favours for her friend while other customers suffer because she is in charge favours her friends 1st .
