I did this recently. I notified customer service when it happened and it took 30 hours to get a response.
Of course, he wasnt even in the recruit pool until the next cycle (3 hours away), then the 1st cycle after he hit he started considering 2 schools. The ticket was acknowledged by cs about 12 hours after I put it in, and he was still available. At the 1pm cycle the next day, he signs with a school and 15 min later I get an email from CS saying "sorry, he signed with another school".
After I got that email, I replied back and told them their service sucks. I understood it was my fault and I cut the wrong player but to sit on it until after he signed with another school and then to just say "sorry, he signed with another school. There is nothing we can do" was horse **** customer service. I would have rather they told me at 7am they couldn't do anything instead of stringing me along and waiting for the easy out. I noticed when I signed in a little later, that ticket was closed and deleted from my inbox.
