INternet only cost

I just paid a bill of $73 bucks and I have ** speed of 15mps and when I checked I am offered 30mps for

Starter Internet	10 Mbps	$29.99/mo.*
Essential Internet	30 Mbps	$39.99/mo.*
Preferred Internet	100 Mbps	$59.99/mo.*

as you can see here.... $40 for double the speed I get for a year. I can dump this internet altogether and jump my internet from my iphone using a jailbroken app I have already and pay just my phone bill and I have unlimited high speed data on tmobile and I have had it for years so it is not throttled because I used to do this for my internet back in the day so I made sure and not get throttle I learned that lesson. But now that I am being legit I get screwed? What gives COx? Drop your rates for us or you will wind up out of luck once we all just go back to our much cheaper and same speed alternatives that do not include you in the loop. I woould like to receive the 30mps deal at $40 for the year please. I will wait until next billing cylce to decide if I cut this scam off.
