Dissatified and Poor Service

It was my husband's birthday on Saturday 26/06/2021 and decided to go to Hungry Lion for their Double Big Boss Burger meal. My husband is not a Burger fan, however, the first time he tasted the Double Big Bos Burger at the Middestad Mall in Bellville, he was super impressed, as he couldn't even finish the meal, that's how strong and juicy it was. On 26/06 we decided to go to the Parow Centre Branch for this delicious meal. When we got their, whilst standing in the line, there was no social distancing, the people was standing almost on top of each other, no one was their to make sure that the people are sanitizing their hands, nothing. I ordered 5 Double Big Bos Burgers, 2 meals and 3 just the Burgers. After a long wait, my order number was called Order 146 and when fetching the order, there was only 4 burgers. I told the lady that I ordered 5 Burgers and she referred me to the Cashier. The Cashier said that it was her mistake, but she will rectified it and it won't take long, but I must pay so long. I paid for the Burger and I told the other Cashier to give me a Double Big Boss Burger. The Cashier that assisted me, heard what I said, came back saying that the 4 Burgers was the normal Big Boss Burgers and not Doubles. I told her that I never buy the normal, always the Double Big Boss Burgers and she blatantly told me that I said 5 normal burgers. I said to her that I always buy the Double and we are all adults, so the normal burgers won't even make us full, hence the reason for the Double Big Boss Burgers. She kept on saying that the order was correct and I corrected her. She then went to the Manager, which was behind the counter and explained to her what happened. The Manager came to the front and asked me to explain to her what happened. I said to the Manager that I will not explain, as the Cashier was suppose to tell her what happened. I told the Manager that I ordered 5 Double Big Boss Burgers, 2 meals and 3 just the Burgers, however, only 4 burgers was given and all normal Burgers. The Manager said that they will fix it and it will take 10 minutes. I paid the difference and told the Cashier that I'm sitting on the other side and to please bring the food to me. I had to swipe twice for their mistakes. Whilst standing by the Cashier asking her whether the order is now correct, she ignored me and served the next customer. I asked her again, is the order now correct and she answered yes, with an attitude. It took more than 10 minutes and eventually the Cashier brought the food and forgot to bring the cooldrinks. My husband had to ask for the cooldrinks. When I opened the box, their was literally little sauce, nothing was really strong and it was such a dry burger. My husband lost his appetite and refused to eat his burger, as he was completely put off by their service. After having my burger, I went to the Manager and told her that was the most dry Burger I've ever had and I didn't enjoy it at all. I was really disgusted with their service. I had this Burger at Bellville Middestad Mall, Bellville Voortrekker Road, Parow Voortrekker Road, Cape Town Branch and never had any issues, it was tasteful, strong, juicy and delicious. I don't order anything else, just the Double Big Boss Burger Meal. There was a lot of people complaining about their service, as they had to wait long for their orders. This was such an unpleasant experience.
