Horrible service at nonna's Italian kitchen Sandton

Most horrible service a customer could experience from the start. First waiting in the line the manager rather serves the customer behind me yet I was waiting for almost 10 minutes then he uses the excuse saying he didn't know who was first. After that we waited till 4:50pm for our food and not even our starters arrived yet we started waiting from 3:30pm. Out of frustration I told the waiter to rather leave my food as I would eat else where and will pay for the drinks I ordered and then again had to wait another half an hour for feed back till I had to walk to the counter and get treated as if I'm at fault the food was delayed then to also while waiting for the manager to communicate with me another customer starts complaining as well saying they had to wait an hour for their food just to receive burnt food and the 1 pasta had hair tangled in it but seemed like the manager wasn't really bothered but I guess whats how they treat their customers
