in regards to picking up open time in IOCC. Do the messages you can send ever get a response?

I’m trying to pick up an open time turn on the afternoon the day before I start a 6 day block of RSV1. IOCC denied me because my required rest was below the 10 hours needed before a reserve day, I sent a message asking if they could move my reserve show time (there are 18+ reserves that day). Will I get a response through IOCC or is that message feature just not checked.
