Poor customer care

I submitted a complaint of ordering a particular burger but being charged for a more expensive item, but received the item.i actually ordered, when the customer care contacted me I explained the situation and provided the receipt but they insisted they also required a photo of the item, I had eaten the item and honestly drive thru, means you are in a vehicle and should not be on your phone let alone taking pictures of your burger while driving, after a back and forth with the customer care person insisting they required a photo to do anything about it, he put the phone down on me
