Complaint Review: Direct TV

I first signed up with Direct TV and they promised a 2 year pricelock guarantee with two year contract.  After the first year, month 13 and 14 bill went up $10 or so.  After that they have literally doubled in price from my initial $40 something to about $85.  I have spent countless hours trying to settle this and absolutely no success.  Last representative actually told me to stop paying.  But I am still under contract and the entire time I have had service, I have not changed my package with them.  Please help!
