@ FPrince,
If they created a file number then I am sure they received your Kit. The Kit is all the forms, CHC is concernd about the sponsored spouse forms. When I wrote to ND to make a change to a mistake I made, they told me there was no file as the Kit had not been received, then 2 days later, bam, KIT arrived and given a file number. I am so sure they stuck this to the side and there it sits for you. On top of that, if its In Process, they obviously have papers to process.
Start putting some pressure on them.
