Hi Joyce,
I haven't heard of this happening. If there was a query with your third request they should notify you that it couldn't be processed & given the reason.
I would put a question to them as to what happened. Did they take payment for all three documents?
Could also be that the third is still coming & is just a bit delayed, but I would think they would have told you that as well.
Isn't doing things online fun:2fun:
Let us know how you get on.
Cheers Peta
