Burger King Midrand is filthy

I have been writing so many bad reviews on Burger King Midrand but no one is attending to it. The service there is very poor, i spend all my lunch hours waiting for food for me to eat at the office. The place is not clean!! I don't think they have a health and safety officer on duty in that store. They bring us our drinks in spilt cups. Today i ordered a Pepsi and it came with a orange lid filled with remains of an orange drink. Basically they got my order wrong, just spilt the orange drink and poured the pepsi inside the same cup. Im not happy at all
