Jiomart — EDD - 26th May and now changed to 29th May

I have ordered few dresses on 24th May and they have mentioned EDD - 26th May and the product is not under process yet. I have attached the screenshot for that. I request you to please help me in this case by delivering those articles. Order number and everything was mentioned in the following screenshot. I want the order within tomorrow. I have ordered it for the function and its on Monday. What will I do if I don't get it on time
