Checking on status of PR application

[p.engineer]

I applied for a renewal of my PR on H&C grounds in February and have since received no word from the authorities. I've tried checking my status on the CIC website using my PR card number and receipt number and in both cases the website is "unable to identify [me] using the information provided (sic)"

Is there any other way to see how my application is coming along? Is there anything I can do to fast track it? I had included a proof of travel as well as a note on the cover saying that this proof of travel was enclosed, however, its been 4 months since the date I said I'd be leaving Canada.

Any help and guidance is appreciated
