I finally got through to the call centre, just by chance, at about 11 AM, a couple of days ago. I was only on hold for about 20 minutes (even though I was told there were 244 people in front of me!). The person I spoke to said to wait until the very beginning of July, and if the passports haven't arrived by then (I mailed the applications the end of April), then I am supposed to call them back and request that the applications they be moved to the local office for urgent service, and we should be able to get them in 10 days. Our flights are July 25th.
