Cold nacho fries

Very disappointed in the food from Burger King Sasol Disa. Everytime without fail when I order the nacho fries it's always ice cold. How do you serve people cold food. When I go to burger King Lorraine I always get hot food. I sent my son back to go ask them why it's so cold, the 1 staff wanted to put it in the microwave imagine that. I won't be supporting them anymore it was my last purchase today.
