Thank you for your reply. The thing is i have never communicated with themDear mkm221,
you don't have to worry about it. They are just informing you that your file might take more time for processing and inviting to keep correspondence with them to a minimum.
do not send too many requests to them and just be patient, things will be just fine. Believe me
Also they didn't specify how long am I supposed to wait for their next communication
