Hope this does NOT happen to you: Our application was sent back last August 2011!!! got lost in the mail (local), spent the last 4 months or so trying to locate it everywhere without success. CPC-M never notified us that they had sent the package back until around December but only to remind us that failure to comply with the "earlier" notice (which we never received because it got lost in the first place, duh!) would mean we were abandoning our application altogether. Needless to say, it's been a rough ride trying to collect all the documentation from scratch, pulling up our energies to build the entire application all over again, etc. Unforltunately, the call centre was no help, we repeatedly demanded information about the status of the application and none of the people we spoke to ever mentioned that the application was sent back, one agent even said that incomplete applications are not sent back if the applicant is overseas, you go figure...
Anyways, you can imagine it's been extremely frustrating, but we've managed to put together a second package with various pieces here and there and hoping that this time around they'll have the decency to at least let us know in advance if the package is ever returned again.
Good luck.
