Anybody else ever get an invoice for a landing at Santa Monica that they never made? I just received an invoice from Vector Airport Systems claiming that my airplane made a landing at KSMO on 1/7/20 and the reality is, my airplane has never been to that airport in the last 10 1/2 years I've owned it. It's never been to any airport in the LA area since I've owned it. Obviously it's an error, but my question is, has anyone here successfully disputed this crap and how did you go about proving their error? How do they collect the N numbers for invoicing? Visually with binoculars? ATC records? I'm wondering how my tail number got in their system. The bill is only $10.96, but I really, really don't want to pay it. Thanks for the help!
