I recevied several calls pertaining to a "federal tax lien" and was asked if I would like some help in resolving it. I tol them that I already had someone representing us and they asked and after telling them they did nothing but slander the individual I hired. I found an interesting article http://nickhartneyea.blogspot.com/2010/11/berkshire-tax-consultants-co-previously.html which pretty much summed up what I had already expected.
