What would be the point of reverting back, though? The older packages contain less HD programming. As I said, you can get the same programming plus a little more, with 4 HD themes, for the same $10. Then, if you want to get the More HD Theme, it's $5 more. If you're not into sports, then you can get just the 4 HD Themes without the HD Sports theme for the same price as the older package. This gives you more HD Channels, and the ability to see more as they come out.
I think your resistance to change may be due to sheer mistrust of Bell CSRs and the fear that Bell will alter or increase the price of the HD themes once you're on them. But if they're going to increase the price, you won't be protected by just having the old packaging. At least not for long.
As for being afraid to mention it to a CSR, come on. They have to confirm any changes they make with you. If they don't, it's considered fraud. If a CSR is going to commit fraud, he/she could just as easily add it to your account without even discussing it with you.
Don't be afraid to ask questions, and don't be afraid to say no.
