Answered the phone. Caller said he was Scott from GGS Air and said his records showed the air ducts in my home needed cleaning and they were offering a $40 special. He wanted to schedule an appointment for the same day. I asked for a number to call him back later and he gave me 866 472-4748. Company's web site is www.ggsair.com.
Was expecting a phone call, so answered. Likely robo dialer because of couple of seconds of nothing.... Person said he was James with "GGSA" and that they are running a special on air duct cleaning. Hung up. Telemarketer that unsurprisingly ignores Do Not Call list.
