DIRECTV Agreed to one thing but was billed for much higher Nationwide

I am a paying Directv customer since 2008.

I called in September 2015 to have my bill reduced.  We came to an agreement; I renew my commitment for 24 months in return I get pricing around $90 for 12 months. 

The bill I received was for over $200.  I was shocked, so I called customer service.  I was told there was an adjustment error, however my bill is nowhere near $90 a month.  I asked them to pull recorded conversation from September to validate my claims.  They stated they are not able to and have to escalate.  I received no phone call so I call several more times, each time I was told they will escalate and someone will contact you.

On 10/30/2015 I spoke with a couple reps before speaking to "Bob" the supervisor.  He basically said nothing can be done and there is no way to pull recorded conversations.  I responded by saying how am I obligated when directv won't live up to their agreement.  He said the 24 month agreement is for the equipment.  I said don't care if the agreement was for the equipment, all I care about the price we agreed to.  I further asked how you know I agreed to the 24 month term, the only way can verify such is if you pull the conversation…  Not being able to pull a recorded conversation is a lie.

Please look into this matter and listen to all the conversations for the last couple months starting with the conversations in September.  The point of me calling in was to lower my bill.  Why would I agree to something if it’s going to cost me more?
