Easyday — Not delivering my order

Dear sir
I ordered some groceries from easyday online app they promised to delivered by 27 April 2021 evening 10 pm but today it's 29 April 2021 till no response from easyday. I called to outlet but they don't have any information about the order. I called to customer care 5 times but every time new person took the call and after case study he replies we will do it fast but not any action from there side
