I have got a courier!

OR MAYBE I HAVE NOT. Early this year, when I changed my company, I got the addresses changed for all the correspondence that used to happen at the address of my old company. I changed it to my home address, which does not change as often as my companies :). Early today I received a SMS that a courier to me was not delivered as no one was at home. I was also given a number to get in touch with. I called them up and inquired about my treasure. I was told that it has been sent to Noida to my office address. Well Well Well. It was fine till now but as soon as he said that it has been sent to my office address, I smelled something wrong. I have not given my new office address to anyone till now so this one had gone to my old office address. So my courier has no address as of now. I told the guys that I can collect the courier from their office address. But they do not allow people to collect couriers from their office (which is rather bizarre). If I can show an identity proof which is well known (PAN card, Driving License etc.) then why should they not allow me to collect courier from their address.
