Ya, i think that GoDaddy gives them some simple guidelines and the account managers get creative. I would just recommend communicating any problems you have with timing etc, they should understand. That is crazy about them calling you so early, they should have known your country timing.
I feel that them contacting us is a good thing, at least they are reaching out and easy to communicate with in this manner. Better than some of these other companies who are pretty well impossible to talk to *GOOGLE COUGH*
Like someone else said, if you don't want them contacting you tell them that. I will probably continue to hear from Godaddy every couple of months i figure.
