Unhappy Customer - Trickery at Papachino's Pineslopes

I would like to lay a complaint against the Papachini's Fourways/Dimitri.

I have made it a ritual to go to the Pizza/Pasta special on Mondays at least once a month at Fourways mostly. As per the same thought we went to this branch on the 1st May 2022 (Public Holiday) We arrived, got seated and given menus to look through order. We went there for the special which showed in the menu provided. The entire table of 13 ordered 9 pizza's and 1 pasta dish. The bill came to (R3 096.50) Noone in this whole time mentioned that the special is not in effect. At end of the meal when the bill was requested, I noticed that the bill was not discounted as expected. The bill came to (R3 096.50) I ask the waiter how come it's not discounted. ONLY THEN he tells me specials are not in effect on public holidays. I say to him that not once did you mention that. I call the manager (Dimitri) who says the same thing. I say to him that's unacceptable that NOT ONE sole mentioned this when we walked in or were seated or when we ordered ONLY PIZZAs and PASTAs.

He tells HO doesn't apply discounts like that's my fault. And I said that's fine but that was not mentioned to me either way!! So how is that its my fault that he didn't train his staff to mention this the patrons? Why it's not mentioned on flyer in the menu. Why was the flyer in the menu at all??? He just says sorry after I've spent more than I had budgeted and to call HO and take it up with them. With no accountability on his part/staff or to correct the major inconvenience caused. He did nothing. He said i should have read the T&Cs on their website. The absolute cheek! It's sad to even think that had I been not black he would have reacted differently (less irritation and attitude) to the issue, but I guess we'll never know.

So I'd like to know how HO will respond to this matter.
