Please Help Me! I just want what was promised. No more, no less.

Hello at the end of my first year of Uverse and internet I was being offered deals with my local cable provider and was considering canceling my service.  I called in to cancel and a person ( a lady ) said she could get us on a plan that we woudl be satisfied with.  She also told me the call was recorded so all i really want is for someone to listen to the call with me.  I agreed to one more year at 87.00 per month.  This included the programming i had which was u200, hd and internet with the equipment i already had for both internet and tv. I was also offered HBO for 3 months. I declined saying either the HBO is for one year or no deal.  She put me on hold and got a manager involved and added the HBO for one year.  She went back through the agreement stating the exact programming including hd service adding Hbo for one year at 87.00 per month.  Now i am being told that she did not say that.  I just want someon to listen to the call with me.  I assure you I am correct.  I declined several times during the converstaion untill she got approval for everything to last one year.  Help me please.  I dont want to leave but I am being oput into a situation with no choice.  It seems rediculous to have to hire an attorney which will cost more that the service but we had an agreemnet and it was recorderded.  Someone please help find a person who can listen to the call and fix this!!
