Two years is a long time to wait! I would definitely go the "unresponsive profile manager" route. I've only had to use it once and it worked like a charm.
Open profile requests also work really well if the dates are far enough back. As the problem may be with the dates, I find it helps if I include the correct dates with sources in a relatives's profile, and then refer to that in the open profile request. When it is clear to the admin that the profile should be open, its usually fixed within a day or two at most.
