Uverse Cancellation Fee Dispute

On 3/20, i decided to close our Uverse account.  I called and spoke to a lady named Eloise.  While speaking to her, I told her that I wanted to downgrade our service to local channels only.  She let me know that this is not offered in my area.  I told her that I would probably cancel our service then. I asked explicitly if I was under any contract or would be changed any fees.  She replied, no.  I told her I would talk to my husband and call back.  Within 5 minutes I called back and spoke to a lady name LaTrevia (or something similar). I told her we, indeed, wanted to cancel.  She said there in fact WAS a cancellation fee of $105.  I told her that I was JUST told there wasn't a fee.  She said that it was a "commitment cancellation fee".   I explained that I have been a customer of AT&T for nearly 20 years, have had several different services through there company and was JUST told I would not have any additional cost to cancel   She told me that I should allow the cost to be assessed and once it's billed, call back in and tell the representative the situation.  She said she would note very clearly that she OK'd it to me that it would be waived.  

  I noticed on 3/21 that the $105 charge was now on my account.  I called yesterday to do as instructed.

  I was not given the name of the representative I was speaking to.  After speaking to her for approximately 31 minutes and she explaining to me that the $105 charge would NOT be waived, I asked to speak to her supervisor.   After another 7 minutes of her telling me that they would not waive this, stating that the computer would NOT allow it, me letting her know that I have several services still remaining through their company, that I have been a loyal, paying on time customer and that I have worked in call centers and customer service positions for over 20 years, that she should waive the fee for customer service sake.  Her reply was, "Since you mentioned that you've been in customer service you should understand that my hands are tied with this..."  I told her that if the computer won't allow the fee to be waived, then she should add a $105 credit to my account, waive the next 3 months of cell charges, or waive the next 3 months of internet fees...  She said that isn't possible either, as those are valid charges.   I told her there had to be SOMETHING she could do to retain me as an AT&T customer.  She said there wasn't.  I, told her that I would be cancelling All of my services through AT&T as soon as possible.  She said, in closing, "And thank you for being the best part of AT&T."  I'm aware that this is a customary closing to your calls, but was a very snarky and rude way to end this conversation.  How can my situation be remedied? There MUST be a way to provide me with a solution.
