I'm in a similar situation; I purchased additional points and sent a certified recession letter, but the new points appeared in my account. I had nine days to send and mailed it within that timeframe but it was delivered after nine business days. I presume they will remove the additional points from my BG account eventually? I guess I might have messed something up, which won't be that big of a deal if true, I just thought I'd wait to add points after more is known from the Hilton Merger.
