I called them, the lady said 'I wouldn't worry something like this'...right.
I sent my package of forms back in February, and it was 2 month before I heard from them at all! My check cleared on Feb. 26th, but by the beginning of April I began to worry and called them.
First they told me it was "strange" and adviced me to get a copy of my cancelled check, to find out the file number which is "supposed to be on the back of it".
Second time they said it was all nonesense, 2 month is nothing unusuall and there are no file number on the back of my check (??).
Few days after that I've got NOA+ EAD appointment scheduled and fingerprint appointment letter all at once, and couple of days after that,- interview appointment letter!
In short,
a) I wouldn't listen too much to what they say
b) I wouldn't worry too much if something takes long, at least not if it is within reason.
Good luck to you at an interview!
Mine is next monday and I will keep you guys posted how it went.
