Ajio — product not deliver on time, also ajio can't track why there is delay by assigned courier company

Address:

Mumbai City, Maharashtra

Ordered 2 products from ajio on 22nd may 19, delivery date was 27th may 2019, however my order has not been delivered till today, i. E. 30th may 2019.
Also in ajio app in tracking history i can see the updates that delivery was out on 25th/26th/27th & 29th may 19 & couldn't deliver due to office/residence was closed, which is a lie. As i have been contacted by courier person on 25th n asked about the time n day to deliver the order, upon which i confirmed that monday 27 should be ok.
Post this i have received no calls from the courier person n also the office was not closed.
Have raised complaint with ajio on 27th, which again got a due date of 30th may, which is today, still it's not resolved yet. And ajio has raised one more complaint having due date of 2nd june.
Pathetic service given by ajio!!!
