It depends how many are in front of you, not just SWO but also all the other designators that have tight follow on school schedules, until they start clearing the backlog from COVID issues it will require patience from everyone. The OR I guarantee you wants you out of there ASAP, no OR likes to have someone just sitting around waiting to go to OCS for months on end.
Did you put ASAP for date available on your application?
There really isn't anyone else to talk to your OR is your point of contact, maybe the processor if you have been talking with them, but that is really it. There have been civilian applicants that have tried to call NRC in the past and that doesn't work well, usually after that happens there is a call from NRC to the NRD CO asking why one of his recruiters applicants is calling NRC.
In the past NRC was pretty firm on request to move out an OCS date or a request to go right away, requests were often met with a response of "If XXX is unable (to go/to wait) at/for designated time then the candidate can submit a letter declining the position.
