False Advertising - NO DOUBLE BURGERS FOR DELIVERY

I have phoned in so many times to both parties. Mr.D says it's Spur's fault... Spur says it's Mr.D, but NOBODY wants to do anything about it. Now Spur has the audacity to ADVERTISE the Spur Double Burger can be ordered with Mr.D app. There is no such option! NOTHING. You cannot add a patty from selecting a single patty burger. There is no double burger. WHAT DO I NEED TO DO FOR YOU TO LISTEN?!
