So I'm supposed to incur a $300 fee for breaking my contract...
No, if they change your plan, you can get out of the contract without fee. However, it looks like in this case, they are not modifying existing contracts. As a current customer, you don't have a complaint until your current contract expires. Then you switch, incur no fee and get the pricing plan you want.
And remember, this is just for new customers.
Doesn't this negate your point about having to switch all your phones and the family plan?
No carrier is any better at this, except the MVNOs, but they offer the absolute worst customer service and overall feature set
I don't disagree. So it's a $20/month customer service charge. Does that make it better? You stick with AT&T or Verizon Wireless because they provide the best overall package for you. But you've got other options, you've just eliminated them because they don't give you want you want either.
shut up and take it.
No, the parent gave you an option - move your business to another carrier. You have at least 2 other choices (Sprint, Verizon Wireless) and in some cases many more (Metro PCS, TracFone, U.S. Cellular, Cricket). What's so hard about switching carriers again?
The rule on staying alive as a program manager is to give 'em a number or give 'em a date, but never give 'em both at once.
