Was lied to back in March about a contract.

Question

Ok, back story.  Back in March I offered to help a friend with a phone line when she was on hard times.  Asked the rep at the store if it would be possible to cancel that line when my other contract was up, by "swapping" the contract to my current phone number.  I was told yes.
Based on that information, I made a financial decision to help my friend.  This was roughly a $45/mo (24 mo) or a $1080 decision based on that information. Called in today and was greeted by definitely the rudest human being that must work for your call center.  Got the vibe based on her attitude that I was being lied to.  Before I could even ask she offered to transfer me to a supervisor which I accepted.
Supervisor gave me the same information, and so now I'm in an awkward situation.  I'll be the first to admit I wasn't exactly nice to your service reps once I realized I had been lied to, and for that I apologize.  On average I use less than 200 minutes, less than 200 texts, and less than 500mb of data.  I've been a customer for over 7 years.  I'm what you would call a "high margin" customer; You guys make a ton of money off me for very little overhead.  That said, I'm not going to be taken advantage of.
As I see it, you have two choices:
1.) You guys can honor the promise that was made to be last March, transfer the duration of my contract to my current #, and I'll just pretend it never happened.  Continue being a loyal customer.  You lose $45/mo + $350 from an EFT I wouldn't pay ($1025 total).  But you keep roughly $45/mo for more or less indefinitely.  I'd even be willing to re-sign a 2 year contract for the old# to accomplish this.
2.) You guys can tell me to get bent.  Now, that would be the end of our 7 year relationship.  You guys would get an EFT out of me, but that would literally be the final $350 you guys ever see from me.  Because Option #2 also includes me getting two ports to T-Mobile.  One for my oldest #, and one for the contract #.  They'd reimburse me the $350, I'd drop the new #, and I'd have my old #.
Basically at this point what you're doing is hoping that I will accept you holding my oldest # hostage.  Like I said, I'm not one to be taken advantage of.  I understand you guys are a business and need to have profitable rates; Good for you, yay Capitalism.  But I think I've pretty clearly laid out the financial reasons you should do this, never mind the ethical reasons.
So how about it.  We still gonna do business?

Answer 1

I was lied to about an option I had when signing a contract.  Either Verizon is pretending that I'm lying about it, or they just don't care.
I wouldn't be able to drop the second line.  What I would have to do is port the non-contracted line, then straight up cancel the other line.  T-Mobile only wants to see that there was a ETF on the final bill, not which number was ETF.  I've already cleared this with them.
I've already spoke to T-Mobile.
They see Verizon/ATT/Sprint do this sneaky crap all the time.
They already told me all they look for is an ETF, not which line was ETF'd.
I WILL get reimbursed the ETF if Verizon foolishly chooses this course of action.
In the end, Verizon can stand behind a promise that was made to me last March.  Doing so doesn't hurt them financially and is the better business decision.  It's also the ethical thing to do. They can make $350 and REALLY **** me off, or $1080 and make me happy.
