Very scummy company. Watching sports with friends when the caller id popped up on the tv. Neighbor said don't ever answer their calls. They "claim" you recently did a survey with them which is why they're following up (trolling randomly). Want to give a free gift (useless trinket) for a short (1 hour+) demonstration (high-pressure sales talk) of their air filters and vacuums. He said they showed up an hour late without a courtesy call and he had to kick them out after 2 hours when the jerk started arguing for not wanting to buy their cr@p. Must have paid for their good rating on BBB but the complaints there and on other websites don't lie. Even their former employees say they are cr@p.
