Poor service, lame excuse, why is the branch operating?

2 weeks ago, I went to a VODACOM outlet at Atterbury Value Mart in Faerie Glen, to cancel my contract after struggling to access the call center. The guy refused to assist me saying they do not deal with cancelations. I was frustrated, then left. Yesterday, around 16h50. I went to the same branch to do a Sim swap. When I arrived, the door was closed but there were two elderly clients. As they opened for them to leave, the same guy said they couldn't help me as they had cashed up. The store closes at 17h00 but he refused to help me.
