Burnt food, bad service and manager ***********

We know the service is generally bad but we go there anyway because normally the food is ok. I have had the new flapjack stack at Wimpy All Saints and Wimpy Bellairs Centres so know what it should look and taste like. I ordered it at Wimpy Northgate on 5 Dec'17 and was shocked - I received unrecognizable, burnt black and totally flattened 'things' that I have no idea how they were actually served. I sent them back and received a plate of dark brown flapjacks that tasted terrible, like they had been cooked in oil. We complained to the manager who wasn't interested at all until I said I was putting my experience on Hello Peter. Then she made every daft excuse including how 'she can't do food control' as well!!! I am so disgusted, remembering the Wimpy's from the early 1970's and having managed restaurants including The Porterhouse, I don't know why there is no training done or quality control. I am mad!!!!
