Cheque is no more a guarantee for return of money...
With a cheque, upon dispute the judge can only give jail terms to the defaulter, there is no guarantee of return of the money. After the jail terms, the person is free to roam around and only condition that travel ban will be in place.

Also a passport can be re-issued telling that it has been lost.

Better ask Relatives, Friends or people who know you.

World has changed and all are updated. For example , if you go outside and search for an open Wifi, you will find none, all have secured their wifi with a password .
