Usually, you have to be standing on one foot (left foot, I believe) while you are juggling chainsaws before you can actually get through on that ridiculous line.
It's probably a moot point anyway, since the person that you'd have spoken to would have provided little, if any, help.
The Call Centre is probably the most disappointing part of `interacting' with CIC; that, and being ignored when you send a CSE, or email to the address that they tell you to use for correspondence. There really should be an elevated level of service for those that have paid the fees, submitted an application, and have a real, genuine question. I can understand the Call Centre `screening/fielding' calls, but why on earth can't a call be transferred to someone with the ability to answer questions, if the caller is a paying customer?!
