at my wit's end with Xfinity customer service

I've about had it with Xfinity.  The instructions on how to DM Xfinity Support DO NOT WORK.  I am a reasonably intelligent person who can read and understand instructions.  I have been entirely unable, despite being signed in, to successfully follow their instruction on how to DM.  Not that it matters.  Xfinity Support never responded to my message from the past when I did pose a question.  I am a platinum member and should be eligible for Peacock Premium.  It is a known issue apparently that affects some Platinum users.  I have wasted enough time with chat agents.  I can't spend hours and hours trying to get help, with all their empty promises.  I need to speak this out on the phone with someone who is competent.  I am at my wit's end with the customer service support at Xfinity.  I need someone at Xfinity who can help.  Been dealing with this for about 10 days now, to absolutely no help.  This is not good for my retention long term for remaining an Xfinity customer, and I am representative of their customer base.
