What can I do if a patent company did nothing with my product?

In 2007 I contacted a company about patenting my product and marketing it they did their research on it and I was granted a patent I am medically disable and on a fixed income I pay a lot of money for I have 2 patents with them they have not got a hold of me through phone or mail. Now just this Friday I see in a good morning local news that a similar product has an account with home depot. I am very upset because if they did their job my product was done first. Can you help me?
