A month and still no feedback from kfc Bluedowns

Kfc Bluedowns is a walk away from my house, every time I go there the experience and food gets really bad. It's officially a month after logging my concerns about burned food, calling their call center, numerous emails and on top of that a manager who was supposed to call and a manager with bad attitude. I won't even give them 1 star, I'll give them zero stars for their service delivery.
