When I called MS a couple weeks back and they couldn't do it. I had to call the passholder line. I waited on hold about 2 hours and then it took about 15 minutes to go through the research/approval process to renew an expired pass at the
DVC rate. I had read elsewhere on the Dis that they were taking your contact info and calling back in about 2 weeks, so I was really happy that they researched it and let me renew all in one call.
