Really sad to know.
Normally the stealer call after 3 or 4 weeks and ask for ransome. They dont call before 3 or 4 weeks as it can be a risk for them.
Agreed with u @KamranAslam...Its planned, and they will call for sure with in a month, as they do it just for ransome amount. Might be they ask for 4 or 5 lacs.
Anyhow our sympathies are with @poster. God will do better, dont worry.
