Yes, check the BBB but don't assume that a "good" report means
anything. I found out from our BBB that they don't make complaints
public. If they decide to change a company's rating based on number of
complaints, that can take years. In the meantime if you go too
seriously by a "good" BBB report you can be misled. Astonishing, but
many state agencies are not forthcoming about consumer's complaints
either. You should ask if they make complaints public, as well as
asking if they HAVE complaints.
