Their app does not record street number and apartment numbers. When you order your expected to know this. The driver looks at special instructions I gave the security code to get in the building. It rings my phone. All I hear is Skip with delivery. I respond I'll buzz you in. Does not ask for apartment number and does not leave order. I paid thirty nine dollars and did not receive. That includes a delivery fee and tip. I complain and am told fifty percent refund as address was incomplete. I am penalized twenty dollars for their failed app and told I could have put apt. Number in special instructions. Even though I assumed they had my full address. I'm supposed to know this. They are rip off artists.
