The fact that you have been waiting for over year without a second line update, could mean that either VO forgets your case (unlikely) or your case needs more time for assessment (likely). In the former case, if you haven't contacted the VO you are encouraged to do so to know where your application is at. In the latter case, best way is to get a GCMS and be patient. If you withdraw the application from FSW now and switch to EE, I don't think you can run away from the same due diligence from CIC. And regarding the fee, from what I know, there won't be a refund.
