The app doesn't let you update your info or put a unit number. I used my location when I placed the order. The driver drove to my place we waved at him but he wouldn't stop or look up from his phone. He returned our order and we were blamed for the mistakes. We asked for a contact number and they refused to give it to us. They only wanted to give me a credit for less than half of what we paid. I had to hunt the number down and now I have to wait 7 days for refund. Worst customer service ever! I wish I could give 0 stars.
