Paytm Mall — my order for fast tag is delayed multiple time

Address:

FLAT 204, WING A2, WOODSVILLE PHASE 1,, Pune, Maharashtra, 412105

I baught fast tage from paytmmall on 27th nov-19 and schedule dispatch was 30 nov-19 but it is rescheduled 4th time from 30-nov to 5-dec and do not know how many time will more. Their contact number is also not in service and not replying on complaint raised.
No clues how to get information or refund of my amount.
My order is [protected]
I tried to contact[protected] and this number is out of service..
This is very ridiculous that a paytm is doing this kind of behavior
