It's not exactly fraudulent debt collection calls, but I've gotten 3 parking tickets for a car I sold six months ago.
The first time, I sent in a copy of the title transfer document, and got a reply saying that the ticket had been dismissed and that they have corrected their records.
Same thing has happened the more recent two times, except all I got in the most recent one was a final warning saying that the first court date had lapsed, and that it would go to collections. Which was kinda scary. I sent in the copy of the title transfer and the previous notes they sent me saying they would correct the records yesterday.
I'm getting annoyed that I might have to take time off of work go to the municipal court (which is about 10 miles away from the town I actually live in, and 25 miles from where I work.) It's just obnoxious that I keep getting sternly worded, legally binding correspondence from the government because someone else keeps fucking up where they park.
