AT&T Throttles $30 Dollar Unlimited Data Plan After only 3GB of usage!! After four years of paying while using UNDER 500 MB!! Dallas, Texas

I've been with AT&T for over four years and because of this I was grandfathered into their $30.00 monthly unlimited data plan. I have the iphone 4. I have always used far under 1 GB of data for that entire time because I was connected to wifi. However as I'm visiting out of state relatives this month who don't have Internet I have simply used my phones data without wifi.

I mean, d**n, I am paying $30 dollars monthly ONLY FOR DATA.. Geez!!

And I recieved a text message today stating:

ATT Free Msg: Your data usage has reached 3GB this month. Using more than 3GB in future billing cycles will result in reduced speeds. You can use Wi-Fi to help avoid reduced speeds. Visit www.att.com/datainfo or call 866-344-7584 for more info.

WTF AT&T!!

I've paid these sky high bills for four years for services I could have gotten at HALF THE PRICE ELSEWHERE and you threaten to throttle me after 3GB when I'm paying $30 specifically for data?!

You should be ashamed! You're already breaking the services down to extract EXTRA each month from the customers! A "LOT" EXTRA! And don't act like I haven't seen all the surcharges and fees that total d**n near what I'm paying for the crappy minutes that I never fully get to use as my calls KEEP DROPPING!!

Your company is ran by GREEDY JERKS and when my contract ends at the end of this month I WILL BE LONG GONE!

And Good Riddance!
