hp hewlett packard — No response from tech support

Website:

I have HP Laptop and I was interested to know if a particular advanced feature is available in that laptop model or not. I called HP Customer support and after 3 iterations finally, got connected to the tech agent. I had to explain the whole story to him. He somewhat understood it but there was no conviction. Then he said he will contact someone and let me know.

But it was going to take some time. I said give me a request number and arrange for a call back from the subject expert. He never gave me a ref number and it's 4 days since no one has called me as well.
Disappointed.
