Perks??

A while back I got an alert from Xfinity saying I could get a free item. I click and there's nothing about it in the app. I spent an hour in a chat asking where it was and they sent me to the perks page to some other thing that wasn't the free item. Then they said it may have expired. I had just got the message. Then it happened again another time. And today I got s msg saying something about reading weekend and $1o off Amazon books or something. So I go to the perks page, it says log in as primary, I click to login and it says page error. Go out and back on, login, go to perks and not s single thing about it. Why do they keep sending these messages out if they're not even offering this stuff and support never had any clue?? I finally got my bill down $30 and they raised the price $10 right after. I can see why people do like them. I'm disabled and took them almost a year to finally give me the discount they had a while back for the ACC or whatever it was. And by then it was done in a couple months.
