Professional Courier — Not delivered parcel

Hi,

This complain is for professional courier in Thane city location.
My some of the important documents arrived from Delhi to thane through professional courier.
I received call from courier office and person asked me to collect the parcel from instead of delivering at my home.
I requested him to deliver the parcel at my home as it was very important.
after that almost 4 days are gone, neither they have not delivered the parcel nor they have even called me once . problem is that i don't have their phone nos. to ask the status.

Thanks & Regards,
Jitendra VIshwakarma
