Did you talk to case officer? If so, how many times and how has been their reaction towards your file status inquiry?
There is no single case officer allocated to cases any more, so you're chances of talking to one are practically zero.
I think there is also a major misunderstanding about how processing works. It is not as if someone is working on your file on a daily basis.
After an initial assessment that you have lodged a valid application, your application will sit in a queue until someone picks it up for processing. If the application is decision ready, it could be processed and decided in a matter of hours. If further documentation is required or if further checking is required, it could drag on for much longer.
Typically, if a request for further information is sent, no one will look at the application again until the 28 day deadline has passed. It may be a different case officer this time and they may decide to make additional requests for information.
As long as the processing time is within global standards, status inquiries will be routinely ignored. One of the reasons you can't talk to case officers about the progress of your application, is that they would spend all day answering pointless inquiries instead of doing their jobs.
If you have genuine concerns, it is best to make inquiries through the recommended channels.
I get the odd client who asks for updates on an almost daily basis by email, text message and phone. While I appreciate that people are anxious about their application, it's extremely annoying and a waste of everyone's time. The vast majority seem to have a reasonable understanding of how the system works.
