Complaint Review: Best Choice SEO

I own a Digital Marketing Company and these guys "Best Choice SEO" spam my clients DAILY with really bad offers. All day long, our emails blow up with this company BS. Do we ever need to go this low to take on clients? Nope - we know what we are doing and don't spam others to try and sell services - which are significantly under priced btw. Telling us they are offering bad services as well as SPAM. 

Do a reputation lookup before using this company. Seems like a few others who have used their services aren't too pleased either.
