Got a unsolicited call from this company. They did not identify who they were with or their name. When asked they hung up! I called back talked to "David" (the same person that called) and suggested proper phone etiquette is to immediately identify who you are and who they are with. They hung up again.
I will not do any work with a company that hires such rude people.
