Very sad to inform you that i have submit the complaint of no sound while doing video calls.
Such a pathetic service support from hp team,
First time when i register the complaint the case no was : [protected]
I was assure that hp team will help me to resolve the issue, but sorry to say that no call from last 2 days after registering the call. Then i called again to customer care they had assured me that tommorrow we will depute engineer to rectify the issue.
2. Again no technician the i called to customer care no and apology was saying by mr. Subash and he has assured me to do the steps:
Bios checking and after that you have to check camera recording. If there is no voice then its a mike issue and he registered a new case no:[protected] and we will asisgn an engineer at your residence.
Again after checking when i called again to customer care no they were telling a new story.
They were telling again to check the softwares and after that mr. Sashi again registered a new case no. [protected]

Again sorry to say no engineer was assigned.

Then yesterday on dtd: mrs. Paulimi again telling a new story to check device manager and other softwares and at and was taken yesterday a lady called was telling the steps to check the software but she had failed and se drops a mail and called me to reply the mail and we will take up the matter on special priority and send engineer to rectify the issse.

I am totally fed up to buy a hp product and as my daughter is missing her online classes and no body is taking so much pain to rectify the issues.

Can some body will help

Ajay
