Narrative:

Attempted contact with approach on 120.12 as directed (3 times), no answer for 60-90 seconds. Maintained 10000 ft MSL as previously assigned. Went to 119.35 as a known approach frequency. Controller said not quite in his airspace, but stay with him and he would coordinate for us. Stayed on frequency 2-3 mins, was called on company frequency and told to monitor 120.12 again, did so on #2 radio and controller said must descend to 6000 ft 'immediately.' frequency 119.35 was busy, so descended to 6000 ft per other controller. Then sent over to 118.4 (same controller was also working 119.35), who asked why we had descended. We related the previous events. No further discussion/issues. Supplemental information from acn 589216: center handed us off to approach. No contact on the first frequency -- went to another frequency from chart, where contact was made. Somehow we lost communication with that controller and by the time we were able to establish contact we were somewhat chastised by ATC for not being in contact. No conflicts occurred to the best of my knowledge.
