***** and disrespectful service

Me and my friend were at Panarottis, we were served by a waiter who was not even attentive when we needed to add more orders. When asked for the bill, we were given and payed the full amount with a card. Later on they 3 waiters came to gang on us to says that our bill was put on different waiters tabs and our money is short. And they said we were given a bill of people who left who were meant to pay R80 but were over charged. How ********** is that. And we were given these two invoices again to pay both for your waiters inconveniences, 2 invoices identical ***9. We asked for a manager but your waiters fought by themselves and never attended our request. After being such a loyal patron, I'm upset by the crowd eye we had to bare, the treatment, I'm upset and disgusted. I deserve an apology and compensation.
