Checkers sixty 60 can't deliver what you order in time .

I placed an order on the checkers 60 60 app. Order no ***. After waiting 60 minutes was informed that the order will take 3 hrs to deliver. When I received the order found that not all I ordered was sent. The chips I ordered was placed at the bottom of the bag and the heavy items were placed on top of them. When I called to log a complaint was told that they can do nothing to help but tell me how to log a complaint on the app. They said that they apologize. I problem is that they made me pay upfront for the items and I have wait 2 to 3 business days for the refund. I was under the impression that 60 60 ment I would get my order 60 minutes after I place my order. I was told that they decide when to deliver and I have no say in that.
