Years ago I briefly had an 800 number for my cellphone. I was getting a ton of calls for the prior owner of the number, and I eventually had him call me. He explained that it was his number, the phone company claimed his payment was late, and he was working on resecuring the number.
Well, I’d already gotten new business cards and stationery made. I wanted the number and had done nothing wrong. I contacted the phone company and they assured me it was my number.
The other guy kept getting calls, important sounding calls. I contacted him again and tried to rationally discuss the matter, but he just started threatening me, insisting I had to call the phone company and give the number back to him.
So I went all out. Every call he got I told the caller they were a cnt for doing business with Joe. I told them Joe was fcking their mother. I basically said whatever horrible nastiness came into my mind at the time.
Joe went away.
