Is Peacock still free for diamond members?

Hi. I had a question about Peacock. Not too long ago, we used the rewards option and got Peacock premium free due to the fact that we were diamond members. We had to move and get new boxes, but according to Xfinity/Comcast, we still got Peacock for free. I reactivated it a few months ago with no problems. However, I tried getting on Peacock today and for some reason I couldn't access half the shows on it. No one told us anything about Peacock not being free. I read that you had to do the rewards thing again which didn't really make sense because I didn't want to get charged for two accounts because I thought diamond members got Peacock for free. I followed all the prompts, but it stated I had to add a credit card/paypal account, and I didn't know what to do. Do I have to call customer service to fix this? Like I said, I don't want to accidentally pick a plan and get charged for it. What do I do? Please advise.
