Here we go again:

Hi xxxxx,

My sincere apologies for my professional persistence while I am having a very difficult time in getting hold of you.

My intention is to know your interest in scheduling a quick call with my Director at your free time. We are not looking for any business opportunities rather we would like to get introduced & make you aware on our full range of capabilities at a global stand point.

Let me know please.

Regards,
Sandeep

In a single sentence he basically said, "We are not trying to sell you something, rather we are trying to sell you something."

Seriously?
