Burger king 3 arts

i have had it with burger king and their staff, i had complained last week after ordering goods for more than 300rand only to have 4 whopper meals made without any flavor added to the burgers. The burgers bought at 3arts were so disgusting that myself and the other three individuals threw the items away, what a waste of money and time as i went in my tea break. I logged a complaint only to be told by the manager that i could have one meal returned to which i have explained that this meals are for four individuals and that wouldnt be fair and that these individuals i would gladly bring along. The manager made as if i had done this on purpose and that im being unnecessary but its money waisted for products that's suppose to taste good based on adverti*****ts and previous experience. I highly recommended BK but not anymore. I would like my complaint to be looked at asap and 4 meals refunded or remade because i made for decent food not tasteless meals.
