Frustrated! Cannot get my free Peacock Premium reward.

Well, like many others, I'm a Diamond rewards member with the free Peacock Premium reward who CANNOT get it! I had it via the 1 GB internet but on January 20th I changed my plan to the 500 MBS internet along with other changes. My other plan changes moved me up to a Diamond rewards member. Since then I have tried repeatedly to get Peacock back with NO success. I contacted support multiple times in the past week and received WORTHLESS support every time. One person escalated my issue and generated a ticket on it. One day later I get a response to the ticket telling me how to activate my reward. I KNOW HOW TO DO THAT! I tried EVERY method I could find to locate and activate it but nothing helped. I CAN'T ACTIVATE SOMETHING THAT IS NOT THERE! It seems no one can understand that. I was a top level Senior Computer Systems Administrator in a nationwide newspaper data center for 20 years and I've dealt with countless support people but Xfinity support I believe hands down is the worst! I've had other Xfinity support failures in the past too...  Yeah, you got it, I'm extremely frustrated. Hence this rant....
