[Resolved]  Bluedart — Asking personal Cell No. to hand over the courier

Dear Sir/Mam

The courier person from Blue Dart comes for a courier delivery from my bank.
He asks me to sign and give my phone/cell number on his delivery record for handing over the courier.
I sign the paper to receive and argues over giving phone number. I say you can check my ID for
verification if I am the right person for this courier as the courier is on my name. Even then he argues for my number. I tell him that I do not give my personal numbers and you show me your rule for asking cell number. I also tell him that even government services from postal department does not ask phone number, who are you to ask my number? He keeps arguing but gives me the courier angrily.

I want to know what is the rule and can they really ask for the number or what does the law say?
Please help as this could serve everybody better.

Thanks
Best Regards
Satyajit Sharma
