When did you call CIC? Just recently?
There is one "gotcha" to be careful about.
I applied for citizenship on April 29th last year. In early July, I moved. So I went to eCAS and updated my address. (I was already in eCAS (even before they opened my application) because I was also in the middle of sponsoring my wife at the time). In a few days, I saw eCAS update to my new address. Good. A month later, I saw an eCAS update to In Progress with information like "We have received your application and send you the Discover Canada book on July 16th" blah blah blah. I also noticed that my address changed back to the OLD one! What happened was when I changed it in eCAS early july, they didn't open my application yet. After I changed it to the new address, they opened my application and updated my eCAS using my address I had entered in the application forms which of course was my old one (since I filled it out in April). So I had to change my address AGAIN in eCAS as second time. After that I was fine. I also called CIC afterwards to confirm and they said they have my new address.
I don't know how many people would hit the issue I hit but thought I'd share.
