Why I Am Furious with Verizon

I have never used my blog as a place to express my dissatisfaction with something... it's not typically why I write... but this has me so upset - I had to write about it.  And I also want you to know if you're a Verizon customer and want the new iphone 5 what you're getting into.
My husband and I switched to Verizon wireless last year because we were having a few problems with service in our home.  We were happy customers with AT&T, but it was important for us to have service because we primarily use our cell phones for personal and work.
We made the switch just before Verizon stopped offering unlimited data to their customers.  We paid the penalty to get out of our contract with AT&T to go with Verizon because we wanted to be sure we had unlimited data.  We planned on sticking with Verizon forever.
Now - VERIZON is not going to allow you to keep that unlimited data if you want to upgrade to the iphone 5 (or ANY 4G phone).
The ONLY way they will let you keep the unlimited data is if you purchase the iphone for the FULL price - which for the phone we would want be $850 instead of the very discounted price that AT&T and other phone carriers offer.  Basically, you'll be paying hundreds more dollars for the same phone.    Not to mention, Verizon charges a $30 upgrade fee per phone.
I can't believe a company would do that to their customers.  We pay so much already for our service, and it saddens me that they are so money hungry that they are going to "change their policy" and go against their word... especially after we paid to get out of our contract with AT&T to get "grandfathered in" to Verizon's unlimited data plans.  We're sad we didn't just stick with AT&T because they're not changing any policies and we would still have unlimited data.
We are going to switch back to AT&T.  Even though it will be about the same price as it would if we stayed at Verizon because we won't have our unlimited data anymore with AT&T because we switched - it's the principal of the situation.  It's discouraging... and I hope they understand that building  customer satisfaction is very important - and "changing your policies" is not the way to go about doing that.
Okay, end rant.  Off my soap box.
Darn you, Verizon!!!
