Sounds like a winner...
Where do I sign up to hand over my money, wait 6 months and then get the same amount back!
MANY folks/decision makers who value their brand/company/business,would never consider associating with a partner who presents a high risk of tarnishing their reputation. Happens all the time in the real world.
When considering third party partnerships, one must weigh the risk vs reward. Just because Ambrosi is doing his job at the moment, does not mean it will always be that way. The man has a long and well documented history of awful treatment of his customers, even posting in a thread where those customers are complaining of being out thousands of dollars. Ambrosi even made a joke about it!
There is no excuse for this guys antics, and, personally, I would never partner up with a guy like that. Just my opinion.
It just blows my mind that a "vendor" would treat his customer this way.
It sounds like you invested thousands, and had Ambrosi done right by you, I'm sure you would have continued to work with him over the long haul.
Ambrosi will eventually burn all his bridges, guys like this always do in the end.
