Worst customer service

Not only has this app kept me waiting over an hour only to find out my elected restaurant doesnt deliver, but 1 time I placed an order by accident--customer service refused to allow me to cancel the order (even though I attempted to within seconds of placing it), but they charged me the full amount without even attempting to assist me in correcting my mistake.
