When we were in San Angelo our number was very similar to a Real Estate Office and a dentist.
The dentist had cards printed that had the right number but because of the font was easy to misread as our number. We tried to tell them repeatedly and were told tough luck. One day a distraught Mother called her child had knocked out an adult tooth. She would not listen to Mom, so I took the phone from her and gave her basic first aide info. Once she calmed down, I told her this wasn't the dentist office and gave her the correct number.
Dad ran into the dentist and told him he had a major complaint. He told him about the cards with the hard to read number. How we were fielding multiple calls from his office daily, and about the hysterical mother. We found out later his office people got an earful from him, he pulled the bad stationary and got new cards. The calls pretty much stopped.
We were one digit different. Usually giving the correct number solved the problem.
One day Mom called me at work and ordered me to get off the internet. (We later realized mom had had some mini strokes). I used my laptop with my dial up at the museum (ISP knew and was fine with it) Mom insisted that I was somehow tying up her line because it made that same noise every time someone called.
I told my boss what was going on, since it was slow he said go check on mom. When I got there I realized it was a fax machine calling. I called the realtor and told them what was happening, so if someone was expecting a fax they should contact that person. They said they would post a number by the fax machine.
Then I called the phone company (this is between fax calls). They told me I could knock the fax machine off auto call by dialing #9876543210. I did that and got an irate phone call from the Realtor that was faxing. He was going to sue my $*#(*#$U&% off if his clients lost the house they were trying to bid on. He had been faxing all day and I broke his fax.
I told him I would testify against him for his clients because he had dialing a private home for several hours. CLICK. The Realtor with a similar number called and apologized to my Mom, even though it was totally the other guy's fault. Seriously who faxes something for HOURS without checking the number or calling to confirm the number.
