Yes, that's a problem. I have seen others post they found a broker to accept their penny stock transfer, and it wasn't one of the more common brokers like you mentioned trying. But I can't remember the brokers name. Maybe scan through the posts and see if you can find a broker others were able to get their stock transferred into.
I'm going to take a WAG and say it likely depends on the size of your account and what the penny stock(s) to be transferred are.
Sorry I can't be of more help and good luck to you.
