Humiliating treatment by Loftus Lupa manager

I arrived at Lupa Loftus Monday around 19:30 pm. I was approached by the manager Sindiso. Since the Monday special of Pizza with beer was not advertised at the entrance, I asked him whether it was still on. He told me that it is not advertised since it would end soon, but that he could still do me a favour to arrange it for me. I was surprised, since it differed from the info at Lynnwood Lynnwood. I called the latter then, and they confirmed that it is always on there. The next move from Sindiso was then to accuse me rudely of still having an outstanding bill. This goes back to a visit about a month ago, when I waited for about an hour for a pizza that arrived cold. I got another pizza with wine, but when I wanted to pay with my virtual card, my phone's battery was flat. Since they did not have a charger for my iphone, I said I would fetch my credit card in my car and the waiter could go with me. The waiter told me the meal was on the house, and assured me he would not have to pay the bill of about R 127. After that incident, I visited a week or two later again for the special. and told Sindiso that I appreciated the previous gesture, but was afraid that the waiter would have paid. Sindiso told me that the waiter would have paid. When he humiliated me tonight, after it became clear that he had given me the wrong info contradicting the info from Lynnwood Lupa, he told me that I after all still had an unpaid bill. I told him he could check on their cameras, who was serving me at the initial incident, to which he did not reply. I asked to speak to the owner, but he said it was not allowed. He then called someone, or pretended to call someone - he said it was his general manager, but would not allow me to speak to the person. With this humiliating treatment I would not recommend Lupa Loftus to anyone.
