Hi Rosetta. I think you know that duplicate profiles would get merged, not deleted. When I look at your contributions list, I see that you have completed several merges and proposed several others. If there is a merge proposal still to be completed, you may be able to find it by looking at the 'Pending Merges' sub-menu item under the 'Find' menu at top right. There's another link there for 'merge proposals awaiting action from you'.
If there was no actual merge proposal, just an e-mail, you'll probably need to wait until the topic surfaces again. We can't see your e-mail.
