if you have money to spend and they are able to do the training ..and they did your initial training too and they still can't "fit you in" then they need to be blacklisted...c'mon AFS get your act together!!!
Blacklist Fail.
Firstly. How is that even a problem?
Secondly. Ever considered they actually could be THAT busy. Go spend a sunny afternoon at any flying school, these places run a pretty busy apron.
Finally. And completely on the contrary, id say the fact they aren't willing to take your money proves how busy they are.
JAMUP
Tricky decision, not sure if AAC are still running the Duchess ZK-SMI and if they are, whether or not they do Inst. Ratings. Or, whether they would be able to sort a SEIR in ZK-JRA or that new fangled G1000 they have there. Id say go in and have a chat with them first.
Failing that, unless there is some other secret flying school I don't know about, or Airline Flying Club now do IR's, I think your hand has been forced. Eagle run a Duchess, ZK-YES and do MEIR's.
