Call and get a email or text confirmation it's canceled

Well, this is almost two weeks old so you probably don't need an answer. I just used them once a couple of days ago and after much searching, it appears there is no way to contact them. They made a $50 error on my order and I am going to have to eat the cost. I sent a reply when they emailed me to rate my driver. They credited me $17 on my next order for the items I paid for and didn't get but I will never do business with them again. They didn't give me a refund! They charged me the amount in my cart, not the amount actually spent in the store! Thankfully I have the receipt. I'm calling my bank to dispute the charges.
