It took several weeks, but my issue was finally looked at by tech support and resolved. They turned off the orphaned services I no longer had access to. They said they had a big backlog of support requests. I'm guessing it might have been related to my same issue if potentially thousands of users started incurring unexpected charges from the changes they made. It took a couple of weeks more to refund the over-charges, but they did follow through and everything is now fully resolved. It was just a little scary when I felt like my support requests went unseen for a couple of weeks or more. A simple post in my support ticket saying they we overwhelmed and might take a few weeks to get back to me would have eased my mind a bit. I did have to pay the overages at invoice time, then they got fully refunded weeks later.
Not sure how to mark this as answered here in this site, but consider this response as me marking my situation as fully resolved.
