<human>: Give me a shortened version of the text

For the last several years, I've been paying 44.99 a month for Cox Preferred Internet.  If you look up the rates in my area, that's lower than it should be.  The reason is that I have a discount through my employer.

Last month, Cox offered me a free trial of Premier for 6 months.  I figured, what the hell let me try it for 6 months then cancel it.  Turns out, this free trial was incompatible with other deals (oops; duh) so they silently canceled my employee discount and bumped me up to the standard cost of Preferred Internet... about 70 bucks a month after fees.  The worst thing, is that speed tests showed that the real-world speed for the upgrade was barely any faster.

No big deal right... I just need to downgrade and have my employee discount set up again.  This is where my fuck-up became clear.  The old rate was grandfathered in.  The current employee discount costs 7 dollars more per month than the old one and even worse, it's limited to 2 years instead of unlimited.
<bot>: I tried to get 6 free months of upgraded Internet service... ended up paying 25 bucks more for a month of barely faster service and permanently raising the cost of my old service by 7 bucks.
