OSS only credits request processing time estimate?

What is the estimated turnaround time for hearing a response on a request to support for OSS only credits?

Travis CI has been one of our top choices for OSS project CI, but with the recent billing change a number of our CI builds haven’t been running for the past 2 days, which is a bit of a problem. Hope to get a time estimate soon, it would be a pain to start migrating builds to another service only to get the request approved in a day or two – or the other side being the request takes a month and we go the entire time without CI tests.
