Who called from 4804412200

This is General Dynamics in Scottsdale, AZ. They are NOT a collections agency as far as I know, and make tons of stuff for the military and other high tech industries such as law enforcement and medical.

This appears to be their main number.  Could be any of the employees just making outbound calls.

Some spanish speaking lady said something then hung up. 2 previous phone calls were unknown and 10110. My exboyfriend has been working with a private investigator and I think they are tapping my phone.

This number is legitimately General Dynamics. Sometimes it also comes on Caller ID as "unavailable"

This number belongs to General Dynamics C4S.  It is not a collection agency.  You may receive a call from either an employee or from their emergency messaging service.  If you have been called erroneously please inform General Dynamics to ensure it does not happen again.
