Send it where? There is no address listed in the link. Also sorry you got all those messages but there was nothing showing they went through.
Lou, I understand that you had no way to know the messages went through. Its obviously some weird software issue. If it told you there was a problem, it shouldn't have sent them. It's no big deal.
Smart people has furnished you the link from the contact us page, that deals with payment problems, which includes our contact information for payment issues. It is on the right hand side of the page, below my picture.
If you would like to talk to me personally, afternoons and evenings are the best time to call. In the mornings I am in meetings and all calls go to voice mail.
