Peacock Premium offer for diamond customer was activated but not working

I activated the Reward for diamond customers to get free Peacock Premium but its never worked for me. Had numerous calls and chats but agents just keep asking me same basic questions and same things to try ... like do you see activate button, did you get an email after to accepted the reward, etc. I keep telling them I did go though the entire activate steps. I just never got Peacock Premium access (re)added to the gmail account I had already had access to free Peacock Premium that had been offered to those with a Flex box that ended June 26th.
