Misleading Offer

On January 6th, I received an email from Xfinity noting that my promotion is ending soon.  Email indicated I was being offered 5 year price guarantee "typically reserved for new customers".  I called the number in the email, asking for this offer.  The agent informed my there was no such offer available to me, however he could offer me discounted pricing for 1 year only.  I offered to forward the email I received; he stated he could not receive any email from customers.  I politely declined.  He indicated he had spoken to the back office and they could make additional/better offers to me, so I got transferred.  

The gentleman who I was transferred to indicated he had no idea I was being transferred and had no background on what the prior agent had told me.  So, I started at the beginning.  This agent had less to offer me than the original agent.  I indicated that T-Mobile had laid fiber in my neighborhood and was offering $50/month for 1 gig service, just like Xfinity was offering to NEW customers.  Since my email indicated ""typically reserved for new customers", I would like that.  The agent said that he could not offer that to me.  I indicated I would have to consider cancelling my service.  He then became focused on cancelling my service THAT DAY - right then and there.  I told him I was paid thru the middle of February and therefore would make my decision by then.  He got pretty nasty and told me if I waited to cancel until then, I would have to pay for another month since the next bill would be generated by then.  I told him that made no sense; he responded "well, that's the way it works around here".  I asked to speak to his supervisor; he indicated the supervisor would not be able to help me any better than he could.  I indicated I'd like to speak to a supervisor anyway, so I was then placed on hold for about 20 minutes.  He finally indicated that no supervisor was available and he could not continue on the call any longer.  He said his supervisor was not working that day, but he would have his supervisor contact me at a future date.  I asked him to have any supervisor working that day to call me back - he refused to do that, so I gave up.

I called back a few hours later, and reached a very nice agent.  She had some 5 year offers for me (the original agent said there were none), but they were much more expensive than that offered to new customers.  She also made me a 1 year offer.  I indicated to her that I could cancel my service and my partner could re-establish service as a new customer, but that seemed like a lot of wasted energy and wasted Xfinity resources.  She agreed that was a choice I could make.

I then received a survey about my interaction with Xfinity.  I answered negatively.  Shortly thereafter, I received an email from "Pete" in Customer Experience at Comcast asking me to elaborate on my feedback.  I sent him the information I described above about my experience.  I've never heard from him again.  On January 22nd, I sent a follow-up email asking him for advice/opinion.  I have still not received any response.  So much for Customer Experience feedback.

At this point, I feel I have no further path to pursue with Xfinity.  I have been very pleased with the services I get from Xfinity, but I guess I'll switch to T-Mobile with gig service and a 5 year guarantee and give them a chance.

Sadly, I am not sure I expect to receive any further contact from Xfinity.  It appears to me they really don't care about their customers.

I'm considering engaging the Colorado Public Utilities commission with the original January 6th email I received and the response I've received so far.

Do you have any other suggestions for me?

Thanks in advance.
