1) If you don't have an imm to your sphere, then even if you write to imms, they might just leave it to a different imm to handle.
2) 15 hours is not much, especially if it is compressed over a short real life period.
3) If all you do is write notes and pray (and not get out there and do stuff) -- note that I'm not saying this is the case -- then imms won't be particularly interested in going out of their way to help you.

Personally I've got to level 30+ unempowered over 80+ hours without hearing from an imm before. Not saying that makes it right, but you seem to be reacting WAY too soon to me.
