We didn't get service

I was at old mutual today around 13h00 there were 3 people working while the 3rd one was on the personal call we waited for more 20+minutes to get help until other clients come asking us are we on the queue i said yes, then the other lady finish wish the customer she was helping i went to her and asked about the procedure she said we must register 1st in order to be served and i ask where ahe point the very same one that was on the phone that she the one to register us, she went to her bht she didn't bother helping us she continue with her conversation on the phone, that other one there was nothing she could do for us, as she was waiting for her next client that have register, we left the store while she was busy on the phone, she didn't valued us as clients, she was so unprofessional.
