["Verizon sent me a damaged iphone and I returned it. Now they're claiming they never received it! I got charged over 500 dollars for it."]
That sounds horrible. I would be so mad at them.
I just had to mail a phone back to Verizon and they lost it and are now trying to hit me with a 550 dollar charge! We're working it out now in trying to get them to not charge me that.
