I'm going around in circles trying to solve an issue with multiple eBay call backs and simply getting nowhere.Is there a way to get past the representative level and on to a higher level?

Keep insisting that you want to speak to a manager. I had an issue a few years ago and eventually got through to a manager in the US who took ownership of the problem, kept in touch and resolved it. I hope you have the same luck although it was some time ago and as we know there have been a lot of changes.
