Internet Price Increases for Loyal Customers (Price Discrimination)

Anyone else just randomly get internet price increases?  When I first signed up for the Internet Preferred package, I had an intro rate for $34.99 back in 2013.  I had that for 3 months, then it went up to the $55.99 a month.  Well, after only another 2 months of paying the regular rate, I got an unexpected hike up to $62.99.  At the time I just dealt with it, but after talking to other people in my neighborhood with the same service, they were all paying different prices, so I called cox and they offered me a lower price ($52.99) for a year, and would lock my old price in after that.  

Well my year of the "promo" price is up, but I see they are still offering new customers a rate of $54.99 which was even cheaper than what I was originally supposed to pay when I first signed up ($55.99).  Oh, and they are now offering a 2 year price lock guarantee.  I feel like loyal customers are being punished because we get stuck with a higher bill.  The worst part is there are very few options for me in my area, so Cox can basically control the prices and set them however they want knowing there aren't many options.  Even further, everyone I know in my area is still paying different prices for the exact same service....and the speeds aren't even the advertised speeds half the time, regardless of time of day.  Absolutely ridiculous.
