A continuous pattern, when will Comcast hold themselves accountable?

Today I experienced the same unacceptable behavior that I have endured at least 3 or 4 times over the past few years.  Having experienced increasing prices and diminished service, I was attempting to look for opportunities to save money on my bill.  I went to the website and clicked on a link to look for deals for existing customers.  There were no deals listed, instead it just allowed me to add, delete, or adjust my current services.  A chat box popped up, and an agent asked to help.  I explained what I was attempting to do.  The agent then informed me they were only available to help new customers, even though I was logged in and working in an area for existing customers.  They sent me a link to chat with someone who could help an existing customer.  The link did not work.  I went back and said it did not work.  They gave me a new link.  It took me to some type of Artificial intelligence site that just kept cycling me through a menu that would not help.  I ended up calling customer service.  That was exhausting.  I asked to speak to an agent, but again just kept cycling through a series of questions.  I finally got through and explained what I was trying to do.  The agent said I could save money by getting rid of sports and entertainment package because it was already included in my TV package.  I explained that I only signed up so I could get Turner Classic Movies.  The agent kept repeating that I did not need it.  I explained that I only signed up for it because previously, an agent told me that was the only way to get TCM.  I said if i did not need it, I wanted a refund for the months and months I paid for it.  Then she said she was wrong, maybe I did need it.  I asked several times to speak to a supervisor.  She came back and said she had found a way to reduce my bill by $70 per month and allow me to regain access to Peacock plus.  I said ok, but I wanted her to email it to me.  She said ok, she would email it to me.  She reviewed it several times and she said the email would come to confirm it.  I hung up and watched for the email, which never came.  I ended up calling back, went through the same circular path to get to an agent.  I explained what happened.  She asked for a moment to look at the record.  She came back and said there was nothing in the notes or records that indicated the agent was adjusting my bill.  She went on to say that there was no offers available and no way to lower my bill except to reduce the services.

This is literally the third time this has happened.  I was suspicious that was going to be the case.  It is so frustrating that agents say things and then don't follow through, or do not have the authority to do what they say.  When this happened previously, I was told the agent did not have the authority to promise what they did, and Comcsast refused to honor the commitment.  Another time, I was told they reviewed the audio recording of my conversation, and there were some irregularities, but they would not tell me what they were, and again said they would not honor the promise.  I do not understand how a company gets away with that.

It is really a pattern of Comcast not valuing their customers.  If someone who represents the company makes a commitment, they should honor it.  They should make it easy for customers to contact them.  And, they should not offer deals to new customers that they will not offer existing customers.  I am going to seriously spend the time necessary to cut the cord.
