Little Caesars

I preordered a deep dish cheese pizza cause they never have them hot n ready like they are supposed to be. When I got there I paid for the pizza and a cold Pepsi with my card. I went to grab a Pepsi and all They had was cherry flavor. So I asked for a refund on the Pepsi. The manager said he didn't know how to refund a card and couldn't give my money back. I asked if I could grab two smaller Pepsis and he said no. Then he said fine and went off on me in front of customers. I will NEVER go back there again! He has NO business being a manager and has a BAD attitude!
