Well, I got shot down by Betty; here is her reasoning:
(03) Betty S: We do have the promotion for HBO and Showtime free for 3 months, however that promotion is not available in your account.
(03) Betty S: You already have HBO on the account that is the reason this promotion is not available right now.
(03) Betty S: In order to provide the promotion deal , you should not have movie package on the account for minimum 6 months to get enrolled under the promotion deal.
Just got "Betty S". Shes a tough cookie, this was my second try, no dice, same reason, I had HBO/Starz promo, so I have to wait a couple months to qualify for the next promo. I don't give up that easy, I'll keep trying until it works.
