two e-mail addresses want communication on one only
I have two e-mail accounts. I used the lesser-used one to register with Bitdefender, and it's a pain in the tushy to have to remember to go there once in a while to look for messages. When I tried to switch notification e-mails, it said the one I entered was already in use - YES, because it's MINE and I told you about it when I registered (tho I don't remember why I gave it to them at the time). How do I get B. to switch over to the account I use more frequently?
