best to worst service

I always visited the Wimpy in Malvern (Durban) all the time because they took pride in the preparation of the food and the service was always excellent. However in recent times they have really drop the ball from being the best to one of the worst. Recently I took my family to the Malvern Wimpy and sat outside so I can watch my child play in the play area. The play area was dirty and one of the slides was broken. Then we ordered fish fingers and chips for my daughter which came after our meals. When it did arrive the fish fingers was burnt and dry, I then called the waiter and showed her which in return brought back another. When I cut the fish fingers it was uncooked, cold and still had water inside. I then called the manager and explain to him that I was unhappy with the service and i want him to personal see to the preparation of the next meal. My daughter just ate my chips which I ordered from my meal and we went home. I still paid for her meal even though she hardly ate. Its sad to see this happen to one of my favorite places to eat and unfortunately you have lost me as a customer.
