Myntra is chor and looters

Myntra is cheater. My wife ordered a watch from Myntra against order no. 1207066-9500955-0159403 on cash on delivery. Delivery boy took the cash and watch was absent from package. Now they are refusing to send watch and telling we can’t help. Myntra chor hai, aage se koi product purchase mat karo. They looted my hard earned money.
