Verizon wireless prepaid

So I bought the iphone 4 in Verizon prepaid section. And today I canceled the service and I have to return the phone but I don't have a return label and I try to get one but you have to have a account with Verizon and I no longer have one. I try calling costumer service and nothing. How can I print out the return label for Verizon without having the account… What happens if I don't send the phone back?(I'm though )

Keep calling them back, or do you have the right number? Get on the computer and look them up online, and contact them. They will send you a label.
