Global Ad Solutions Selling totally ineffective or non existing product. Internet

Used GAS ON AND OFF SINCE 2009
Decided to track my emails.
achieved 3.5% with most senders.
Zero with GAS.
Re built whole tracking system.
Same result.
Wrote, nicely to GAS FOUR TIMES.
Last message had mild threat.
Amanda nervously replied showing that they
do not know what is a referring Url in tracking.

They think the target Url is the referring url.

How can that be ? 

That shows that they know that the emails are never transmitted.

WELL WELL WELL!!!
I BELIEVE THIS IS JUST A VERY CRUEL SCAM AND SHOULD BE CLOSED DOWN.
