You may be way down the list, but just as is the case with tyefly - if you're lucky enough to get that 6/6 call, and your file isn't up to date, they'd skip you. The burden really does fall on the patient.
Oh, no, I don't think calling in April next time is a bad idea. Don't wait until the middle of July next year, that's for sure! I started trying to schedule the surgery I wanted done the first week of May by calling in November for the first available pre-op appointment in January. I still didn't get in until the end of June!
mine has never asked me to come in yet and it's been a year, I ocasionally do get letters though for me to fill out forms to update stuff and send back which I do.
