HP India — I am complaining about laptop camera.

Dear sir/Madam,
I have purchased a laptop of model no. TPN-C139. But the experience is not as pleasant as it should have been.the camera like on off on off during the working conditions.it shown as "we can't find your camera".

I am very disappointed by these product, because the camera was not working properly since starting. Due to this I lossed my career based online exams. I went(twice) authorized service center(Karim Nagar) also but the issue was not resolved. I also contacted the toll free no. However, the problem was not solved.
Anyway I won't complain anymore. I just want you to schedule a time for me so that i could either visit your store to pick up a brand new laptop of my choice from your store as replacement, or you will make full refund to me
Yours faithfully,
Kavitha D.
