VERIZON Apple iPhone 4S bad ESN

I had just listed a Verizon iPhone 4S newest model,this was bought by me.I had seen on the listings some cells have bad ESN,I took my phone to Verizon,who than told me to contact customer service,& I did.The phone had a bad ESN,they can tell when you have a phone with a bad ESN when thye type in the MEID number,I did put that in my listing bad ESN,BUT I took it off ebay ,Verizon is so impossible to work with,if someone dont pay the bill,and you buy the phone your out the money,As a seller I couldn't see doing that to anyone.I would love to unlock the phone its never been used!
