They called my business this morning by asking to speak to owner that hasn't been here in 20 years. I told the caller she has the wrong number. She basically called me a liar. "Isn't this a business? I'm trying to reach the business owner. Why did you tell me I have the wrong number?" I just repeated the question she called with. "You asked to speak to *** ****, you have the wrong number." She had a very poor attitude.
