LDC Collection Systems, San Francisco CA SFMTA/Municipal Transportation Agency bogus parking citation San Francisco, California

My husband & I just got a Notice of Delinquent Parking Violation in the mail, for a Citation supposedly given on August 1, 2012 at 7:43am, for a street cleaning violation, cost is $62.00. The Notice requests we pay LDC Collections Systems at a San Francisco address. The citation also shows the address of SFMTA/Municipal Transportation Agency.

I looked up the Citation on the www.services.sfgov.org  website, thinking this was a scam, but it even showed the citation. This is bizarre & impossible.  We haven't been to San Francisco & neither has our car. We live over 6 hours from this location. I was recovering from adverse affects of antibiotics, that I had to take for Pneumonia. My daughter had ballet class at 4pm that day. 

The Citation lists our vehicle as a Nissan MA (I guess that means Maxima...which it's not). It shows the correct license plate number, but does NOT list the color, Registration Expiration OR VIN number...as specified in the California Vehicle Code. My VIN and License/Expiration can be seen, so they cannot claim it's not visible & this citation doesn't list the information couldn't be seen.

V C Section 40202 Notice of Parking Violation:

The notice of parking violation shall also set forth the vehicle license number and registration expiration date if they are visible, the last four digits of the vehicle identification number, if that number is readable through the windshield, the color of the vehicle, and, if possible, the make of the vehicle.

I have seen many bad reviews of LDC Collections, from different states. I don't understand why they are still in business.
