Were you a pre-June-2010 or post-June-2010 applicant?
Certainly for post-June-2010, if your application fails after the completeness check at CIO (and I presume it must have gotten at least past the completeness check for you even to have an ECAS status) then you will not get any documents back. CIC keep the documents once a decision has been made.
Regarding the fee, you will only get a refund if the application did not go IN PROCESS, i.e. did not get past the visa office eligiblity review and into background document checks. Can you remember what your ECAS status was prior to DECISION MADE?
