Burger King rotten customer service

Burger King, doesn't seem bothered about their customers A little ago I put in a comment on one of their products ..it was the new vegan veggie Burger.. The advert made it look nice and flavorsome, so I was eager to try it what I got was a very unpleasant eating experience,, a bland tasting piece of cardboard, the only flavorsome thing was the salad dressing When I noted this to Burger King not once did they acknowledge my feedback, I was asked to send proof of purchase etc Which I duly did, all I got backvwas a continouse please send proof of purchase etc, a number of times then the issue closed.. There was no effort or response as to how the problem would be resolved..I had wasted nearly R70 on this meal Always a loyal customer before this..the lack of even engaging in a constructive talk or resolve.. Had I been in charge I would have at least offered a resolve for my customers dissatisfaction Total lack of customer service No conversation
