When you call/send an email, you need to be as polite as possible and not have a trace of being angry in your email, and you'll go further.
One of the guys in this thread started an email with this...
"Hello, I would like the contact number for Verizon Corporate. I am having a bunch of problems with several of your call centers. Some of which include: Incorrect information, Unreliability, Hostility, Lying to the customer, Incorrect tones with the customer, hanging up on the customer, Unwillingness to cooperate, Repeating the same information, and a ton more."
I know if I were a CS rep, I'd basically tell you to go **** yourself, because in that beginning part, you sound like a condescending prick. With that being said, I have an Eris, I have a 4th one I got on friday sitting here on my desk I'm sending back Tuesday (never even activated the phone), the same day I'm getting my replacement Incredible in the mail.
So yea, I am going from an Eris to a Incredible, and here is how I did it...
Every time I needed a replacement, it was for the same thing (Trackball issues). I would call up, say it was bad, and they would have a replacement in the mail in two days. Done and done. I never ever said a damn thing like 'ARGG I NEED A NEW PHONE THIS SUCKS ARGG SWDFSDFSD", and for two reasons.
1: Everything involving the phone and the warranty is supposed to go though HTC, Verizon is acting as a middle man to make it easier for us.
2: I didn't want to sound like an entitled prick...
In the meantime, I wrote an e-mail to Verizon customer service about how I keep having these problems, it's a hassle always restoring my phone, but not once did I mention anything about any type of upgrade. At the end of the email, I said sorry for the long rant, sorry if I came across as rude at all, and if they had any kind of trackball-less Eris phones (I know there isn't, but still...). The end of the email, I once again said I have NEVER had a problem with any verizon CS and I am extremely pleased with how I have always been treated.
So I send the e-mail, and I get a call the next day saying how she read my email, and could understand my issues, and thanks for being polite, then she said this, verbatim, "I noticed you asked about the incredible back when you first started your contract. Want to be upgraded to one for free?" I of course said yes, we got it all done, and it was shipped. I asked for her name, talked to her supervisor about how she was an absolute help, then we hung up.
I got the tracking number the next day, and it'll be here tuesday (Was two day shipping, but weekends and the holiday coming up).
The whole point was I was never condescending, never sounded like I needed an upgrade, I just tried to work with them in the most respectful manner I could, and it worked for me.
You always catch more flies with honey rather then vinegar. Now I realize that not all of your experiences will be as good as mine even if you're the most kind and understanding person in the world, but starting an email with "Hello, I would like the contact number for Verizon Corporate. I am having a bunch of problems with several of your call centers" never ever pays off.
