I got a call on a recorded line saying it was verizon collecting a debt. They said they couldn't put it on my credit report which was a red flag cuz verizon was on my credit prior. Then she kept asking for my address and other information. I said i wouldn't give my info to something this suspicious and I won't be answering further questions. She said I'll dispute this for me even tho she kept saying I need an address. At the end all of a sudden she didn't need it. It's a scam don't be fooled
