Weather Station ID

Anyone know how to go about getting your WU station ID changed. Would like to use my old ID that I had setup under a different account with an old email address that I don't remember. Bought a new weather station and had to setup a new account to add to WU. My old ID had a low number on the end because I was the first to have a weather station connected to WU. I've tried emailing WU support but get no response.
