Don't ever book your consignment from GMS Express, Though they promise to deliver within 48 hrs any where in india, but they take anything between 6-10 days. Even within city couriers take 3-4 days for delivery.
If you call them to find out or complain they are most unprofessional and every one from the customer care people to the AGM are ready to fight with you.
So use this courier only if you are willing to pay for a courier and get the service of a normal post.
