Ekart Logistics — Product not shipped

I ordered a printer in Flipkart on 16Jul2023 and promised date of delivery is 17Jul2023.
Product is shipped to nearest hub and now at 7PM Flipkart changed delivery date to 20Jul2023.

Nearest hub is hardly 3 KMs from delivery address and sill thy are delaying delivery of product by 3 days.

Worst ecommerce Flipkart and logistics Ekart .
Action should be taken on both companies.

Flipkart just gives standard answer " due to unforseen/operational issues your order is delayed".

And coming to Ekart, none of customer care numbers available in website are working.
