It's a complete joke, they're government representatives and shouldn't be doing this, or know not to have their volume all the way down. I make calls with my phone all the time, in fact I had just called two people in the hour before. I even downloaded an App to test my sound quality and I could hear myself crystal clear. The Agent also conveniently waited until after I fully introduced myself before saying he "couldn't hear me".
Guess I'll have to call again tomorrow, but I'm definitely annoyed as I tried calling 12 times today, and the one time I got in and sit in queue for 32min. I get this.
I feel my case is urgent as I'm starting to strongly suspect my PPR/landing appointment e-mail was sent to the wrong e-mail address (that I unlinked from my account 1.5 years ago) and of course you can have an application rejected for not responding to these e-mails. Webform CSE however has a response time of 2-3 weeks.
