A friend of mine waited the time they suggested, I think it was 3 months. Then, when she called them, they said if you don't hear back please wait 6 months. At the end of the 6 months she contacted them again and they said they never received the MS. She had a receipt signed by somebody in the company, but it never got to the intended agent. Needless to say, she needed to resend and wait out those months again. I believe she went somewhere else, cursing the unprofessional attitude of those she dealt with at the first agency. I would send a polite follow up.
