Order not delivered

I ordered groceries on the app on the 29th of March 2021, and an agent from bottles app called me at 12:15 and advised me that the store was closed due to unforeseen circumstances and couldn't deliver my order for that day and that they would deliver it the next morning. Even apologized for the inconvenience. Now when i email them to ask about my order, i'm not getting feedback on my order and no answer on their phone line.

this is really frustrating its either you deliver my order or refund me back my money
