Thanks to everyone for your kind replies & helps. I was quite worried & didn't have any information about this call. After reading all these answers, now I know how I was picked up by error and what should I do in respond to jury. I am going to mention my current status on jury questionnaire form and send it back to them. Besides I will call one of the rep to inform that. Hope they will send me some kind of confirmation in return.
Thanks again to our VJ members. I am blessed to be a part of the VJ family.
