Useless App!

This is the most useless app ever!
It only works well when it give you notification for their specials (which is really not special at all!)
but when you try to contact their customer service for complains, it cant even locate the store when I was waiting in drive-thru line for 17minutes. Enough time to write a review on the Yelp app, which worked fine!
I would never download this app again!
