D-Mart / Avenue Supermarts — booking error in your server

I would like to state that i am trying to book the order from your portal from last 4 days, midnight between 1200 to 1245am but every time it shows error, as you are aware that as per the current situation we cannot go out and buy essential products. Earlier also there was complaint lodge personally by me at mira road dmart for cheating with us pertaining at the cash counter.
At present also the time slots are open for 30 april, but the comments says oops something went wrong pls try again. This is happening multiple times and fed up of doing online.
Kindly find the screen shot attached below for your information.

May i request you to kindly look into the matter and resolve asap.

Thanks and regards

Wilfred
