Hi, Dan!
The misspelling of Colombia, is really common for English Speakers, not a big deal, unless you are a Colombian (who for sure, like to see their country's name spelled the right way).
In any case, this is it:

Unidad Administrativa Especial de Aeronautica Civil
Aeropuerto Internacional El Dorado

Two other numbers, but not sure if they are working numbers:
Telephone: 571-413-9376
Facsimile: 571-413-8091
^^^^^^^^^^^^^^^^^^^^
This is the government ministry in charge of Aviation:
