I got several answers from the agents.. One of them said they dont give any information to people calling from outside canada, other one said that they dont look after the economic class applications, one of them directly ask me to email the query and he said that was the only i could get to know about my status etc etc..
The best way to ask is be like really polite greet them good morning and just talk point to point i directly said that i was after my UCI number if you could please help me get one.. i wanted to know the status of my application .. thats all i spoke and the lady who directly asked me my name, DOB, place of birth thats it.. she didnt even ask my my date of application..
All the best! I am sure you will get through it ..
