Dell India — Inferior service quality of dell service center

Address:

Gurgaon, Haryana, 122001

I got my laptop on 06th juje from dell service center at sector 14, gurgaon.

I regret to tell you that one problem is resolved & another creeps in. Before handing over the laptop the speaker sound was interrupting, but after receiving the unit the interruption is resolved but the sound of my speaker is considerably reduced; i can not even listen to an audio when a video is running.
I'm very much dissatisfied with dell service. The service provider was not able to provide any kind of support in this regard.
It seems i haven't really made a wise choice of buying a newly launched laptop.
I don't how much importance dell give for customer satisfaction. I need an immediate solution as i have wasted a lot of time on this.
Apparently, they provided me a tracking no:[protected]-31466736; but there seems to be no response from either end. The real sufferer is me here.
A lot of my personal works is being hampered by this issue. Hence, need proper support to resolve this matter urgently
