Indian Army — Splendor Bike

Address:

Darbhanga Bihar

My father have seen a post on internet, about a bike slender plus on sale, BR33AH9936. When he contacted on ([protected]) Mr Ashutosh he introduced him as a army hawaldar based in Ranchi Army Canteen. He pushed to give his bike for 25000 rs with home delivery.
After very insisting my father payed him 4100 rs which he was showing as a delivery chrge and said once you will get the delivery you can pay rest balance amount.
After continued 3-4 days he started making excuses for non delivery.
Then i tried to call him with different number and got to know this is being scammed on a high level in the name of India Army.
My request if any one can help me please help.
And also please don't be in this trap.
