I received a defective modem--literally the device could not emit a wireless signal beyond 20 feet. I asked for a return box from Verizon and promptly returned it in the box (free shipping) supplied. All good, right? Nope. Months later, i am being charged for "equipment not returned". I spent 3 hours on the phone with Verizon--no one could locate my account. After 2.5 hours, someone in NY found my account and I was transferred to an account specialist. In my 3rd hour of Verizon chatting, I was humiliated and insulted by "Robert" who gives no last name. I reiterated that I received defective equipment and returned the equipment with the Verizon supplied box (and there is a serial number). He insinuated that I was lying. I have never been so disgusted in my life!
