Jiomart — No delivery and delaying it to the next day

Website:

I ordered a Boat earphone on 18th of June by Jiomart and today is 30th of June and I still haven't received my product and the order status is again showing it will arrive by tomorrow, it's saying it will arrive Tomorrow for the past 10 days.
I am annoyed by the customer support as well as they promised me each and every time that it will be delivered and no result of delivery seen.
I have mailed them called them and even chatted withe them, the only thing they is I am sorry we are sorry but not doing the actual work that is supposed to happen.

Disappointed and disgusted with Jiomart service
