How to get customer support from VRBO?

I'm an owner who's listed with VRBO for 3 years.  This year I renewed at a "lower" subscription level...had to make a phone call to do that, as the online renewal process didn't allow that option!!!  Frustrating.  THEN I kept getting emails saying I hadn't renewed, even though my credit card had been charged for the renewal.  14 days later, including an email back to customer support and two phone messages (I CANNOT GET A LIVE PERSON TO ANSWER THE PHONE) they have removed my listing, even though my credit card was charged for the renewal.  What can I do???  This is UNACCEPTABLE!!!
