It was my daughter's...

It was my daughter's birthday 30th of May ... we ordered 25 pizzas , only to find mops in our pizzas . Dirty mops , they uses to clean their oven with according to what they said as to why are there are mops in our pizzas . What if it's the same mops cleaning floors and toilets . I'm so disgusted, my son got sick, my daughter got sick and we still waiting for a full refund , the Restaurant is offering us 50% discount after we ate mops in their pizzas
