Vaal Mall cell-c staff think they doing us (paying customers) a favour

I went to the cell-c store at the Vall Mall today 19/01/2018, in general the service is pathetic, I already complained twice to the manageress and she said she agrees with me, but nothing was done, anyway so I always budget for 2 hours of time wasting at that store. I wanted to follow up my my ****** phone insurance claim. I waited exactly 1 hour for a available phone, eventually after 25 minutes of holding the lady on the phone wanted my ticket number, by this time my phone had died, I wanted to log on my email, and asked the staff if I could use a computer they said they had no internet access, so I used one of the display phone, while logging onto my mail, a rude staff member screamed at me "no surfing" I tried to explain her but she didn't listen by then I also lost my cool. We had an heated argument and she said she doesn't care I can report her, she as no customer service at all, it looks like she is a Barbaric animal from the wild, no remorse or anything, I want action taken against this person and a follow up, or else I want to cancel my contract. I spent almost 2 and a half hours in the store.
