Back in May/June 2015, I updated my modem because the old one wasn't working. The rep I spoke with (who I could hardly understand), never mentioned returning the old equipment. I was then charged $79.00 for unreturned equipment. I made several phone calls and could never get an answer. Finally I talked to a rep who then mailed me a box to send the used equipment back to Verizon. In October I mailed the used equipment back via UPS via the UPS label Verizon sent me. To this date, I have not received a credit on my bill of the $79.00 I was charged. I can't get help thru the Help Call center. I just get rerouted. Tired of dealing with this!!! Verizon, your customer service needs great improvement!
