Some Indian sounding loser called to tell me that my AC needed servicing. He asked for me by name, which was surprising. I asked him when the last time they serviced my AC was and he said six months ago. It's funny because I had just remodeled the house three months ago and that included installing a completely new AC system. He said "That's bullsh*t". I told him to go f*** a cow and hung up on him.
Caller (who sounded young and inexperienced) asked if we needed an air conditioning repairman. He said: "we'll be in your neighborhood this week, to give you a free air-duct/vents/filter cleaning", etc. Told my SO to hang up. Sounds scammy.
