I dont' know the specifics about your case so I cna't comment but very unfortunatley it's not at all uncommon to hear complaints like this - very lenghty delays, a complete lack of communication, hosts left uninformed.
I think ringing the radio station is an excellent idea, especially if you can be pithy, factual and unemotive.
The company hates bad press
Some hosts report that they get better quality support by using Twitter if that's any help
Hope this is sorted for you soon
Regards
