Hi Pal 3580 .I think you should in this forum start a new conversation on PRC renewal topic ( or PRC renewal timeline 2019 topic ) and address your question to these two very senior members : Leon and depenabill . You may also address me so that I am updated as well. Leon and depenabill are very knowledgeable and will reply you within 12 hours or so. They would give you v.good advice. Pls write full details of your case.
I am not expert but I think you should not wait and call Immigration on the same phone number right away without giving reference of your previous phone conversation. Before that pl check status of your application on line.
You may also submit a web form . Pls see this :

Have you checked your application status on line ? If not , pl do so . If yes what status it's showing.
Did you create a secure log on with cic to check progress of your application ? If not pl do so. If yes what's it showing .
Also pl have a look again on the PRC Renewal application guide on the topic : What Next after mailing you application.
How many days were you absent in the past 5 years counting backward from the date your application was received in Sydney Nova Scotia ?
Hopefully you will get your PRC within a week or two if you had more than 730 days in Canada in preceding 5 years. Best wishes.
