Davision review: Service, not doing what has been said

Since 2009 I hired Davision to help me with my product, I have spent over 14, 000.00 and they still only call me once a month with the same answers, this is what they tell me every month"not yet Adell, no one has responded to there letters.. they say that they have to be registered in order for them to help me. Like Home Depot says they want to buy my product, I found out in 6 months later. So I ask for the people they are dealing with, they give me the same names all the time. Like when I call, they always say we are still waiting for someone to respond. I gave them names of companies that can help me with making my product, they always say" well they are t registered with Davision and so they cannot use them. Come on. This is ridiculous, it's the same thing everytime. I have to send money to uspto every year for my patent so no one would take it away from me. I have been trying to help Davision, they always say they need to be registered, it's not fair to me. Because I paid 14, 000.00 already and you cant help me. That's my money they are messing with. Yes I need help for this.

Thanks Adell
