.
30th May delivered to Sydney NS.
AOR on July 5th for all 3 application.
July 7th my application was approved and I can see status they mailed my PR card.
July 11th I received PR card.
From July 6th till Sept. 10 I called number of times for my kids PR card and raised couple of web form also.
Some time agent told printer issue.
Some times agent told agent will work.
after 75 working days one good agent told they should escalate this and he did. SLA was 20 working days.
And OCT 16 I received PR card for my Daughtor.
After after OCT 16 till DEC 25th my wife called 3 times to IRCC and finally one agent again escalated her case. He also told SLA 20 days.
Today receive mail her PR card is mailed.
This IRCC is way hard to deal, no escalation process. We just have to keep calling and its luck when we will receive Card.
