I had assumed the same.
So, we contacted MetLife Stadium (201)559-1515. The person who assisted in our phone call was very polite. The person asked why were there so many people interested in this company, that they had been fielding phone calls all morning asking about ISBG.. WOW... Then he said, "It's just funny they act like it's some big deal, but basically anyone can be a MetLife Stadium Partner." We asked how much was paid for such partnership. We were told they couldn't disclose but could connect us with the Corporate Sponsorship Sales Department to discuss various participation plans.
We then contacted the New York Jets. Also, very helpful, the person didn't know anything about ISBG, would offer to connect us to the Director of Corporate Sponsorship, but at this time there's not a person in that position, but they are accepting resumes (so if anyone looking for a job here's one)
Next, we contacted the New York Giants (201) 935-8111. Again, a very nice person with a great Jersey accent. Had earlier calls on ISBG, but doesn't know anything about them.. Didn't offer to transfer to anyone else..
So, we called ISBG at (832) 390-2782, their number on ISBG website, but it's no longer a working number.
Then we contacted the property management for 700 Louisiana Ave, (713) 334-0181. Confirmed ISBG/DKTS do have a virtual office in the building. Again the receptionist was very nice told me they hold meetings, but she has rarely seen anyone associated lately.
So, in a final attempt, we contacted ISBG through twitter about the big announcement. ISBG did respond, asking if we were shareholders of record, which we are through DKTS. We responded and the response was contact our lawyers. We responded, no problem, who are your lawyers, we know of three different firms you have claimed.. No response yet.
