HP Laptop, Model 6720 — harrasment

Regards

sir/mam
I hav submitted my laptop in hp center in okhla due to problem in DVD player on 20th dec 2008.
I hav spent lot of money in visiting the center, to call them, but till yet i hav not recieved my laptop.
They are just making fun of me, treating me in a careless way.
My complaint no. is [protected]. During the period another cases regarding DVD problem are solved but not my.I am on the edge of my patience level.

Kindly suggest me the needful way.
