Fnf from bajaj finserv

Dear Sir, I am going through a very bad experience after giving my resignation with Bajaj Finserv. Need a few clarifications pertaining to the same. 1. They have forced me to keep the laptop that was alloted to me on my last working day. None of this policy is mentioned in the appointment letter. I tried my best to inform them that I cannot take the laptop and pay for the same. I have communications sent out to the HR requesting for a break-up of a hefty amount which includes the Laptop and Notice Period. They have also sent me a Court Notice where both the Recovery amounts are not matching. While I completely understand that I need to pay for not serving the complete notice period, I am not sure if a Company can force an employee to keep a Laptop and then force him to pay. Also, the Court Notice says that I have intentionally kept the Office Asset- Laptop for my personal benefit. Please advise me on this.
