I got the below reply via email:
"Your passport has been received at our office and will be returned to you shortly. We are currently experiencing a high volume of mail intake and we cannot confirm how long this process will take.
Your documents will be returned using the envelope that you provided. If you have followed the instructions on the website and kept note of the tracking number, you should be able to follow its delivery online.
We thank you for your patience.
.....
*Due to a higher than normal volume of emails recently, we ask that you keep correspondence with our office to a minimum.*"
. I guess I will have to call them next week then.
@lprabhjot: Thanks for the number.
