Jio Mart — Shipment delivered late

I have placed a order from jio mart on 15th March of 30000rs and it was suppose to be delivered on 19th March but today it's 24th March still my order is not been delivered. I tried calling to customer care multiple times and no proper response from them, they are not ready to give proper solution to my problem and simply one customer care person is saying it will be delivered as soon as possible. I also tried reaching out to the *Delhivery* service agent also they are very much careless simply saying the order is not yet reached to their place but for me it's showing it's already reached my location. Waste of time for me to connect with multiple people for one order delivery. I was thinking that I have placed a order in a reputed platform but got bad experience. I wanted to get this issue to be noticed by people and they should not face problems like me. Please resolve my issue.
