Bad pink Burger King Burgers

Bought a family meal at the branch at Grandwest Casino and found our burgers raw inside. We then proceeded immediately to burger King only to find after shift changed the new manager refused and said we bought the burgers the previous day. Bear in mind that footage is available for that but the insinuating thoughts of what the manager had we had to listen to and endure untill she finally took it and probably just re heated it and left us with the words that she doesn't believe its raw up untill we eventually left. I think it's pathetic service since we went home already and drove all the way back for a argument with the bad management team of Grandwest Burger King.
