Billing then Bad Attitude from AM Pitso

On the 07th April went to KFC to buy food & swiped to pay for the meal, the transaction went through but the cashier claimed it wasn't showing, Pitso was called & I explained that I got a notification but he came with an attitude saying the system should have picked it up if the transaction went through as I claim. I showed him a message on my phone as proof but he ignored it & continued to swip my card again, when I questioned him he then said if the 1st one went through the 2nd one will be rejected by the bank automatically. Yesterday I checked my statement & saw that I was billed twice for the same meal. I went to Chris Hani KFC & Pitso was called he refused to come meet us & had to walk to the back to find him, when we eventually found him he refused to look at my statement but what I got were insults from him & he told me that he will never help me cause he doesn't control thie network nor the bank. I stay in Boksburg & drove to Vosloorus to resolve this only to be insulted in full view of some of his staff & passby people at the mall. I want my refund & an apology to me & my sister who have been dealing with this man's attitude from day 1
