HP India — laptop repairs

I gave my hp laptop for top cover damage on 15-6-18 for repairs at your
ADYAR service centre (adjucent to viveks) and took delivery on28-6-18.
The said damage is rectified. I also paid Rs.8591/- Now when I checked with
the CD performance it is not at all worked. I again went to your service
centre with lap top. Your staff cleaned the CD compartment and inserted
two old CDs of mine which were hitherto was working. Your staff inserted
one of their CDs ad it was working. When I brought my LT to home and tested
with various CDs. None worked. I am now upset.
Kindly advise me further without any more expenses. My bill No. is 217.

Sincerely,
R.Gopalakrishnan
