I returned my Internet Gateway on July 5 in the box with the label that was sent from Verizon. I received my bill today and it shows I am being charged for the equipment due to non return of items. I have the Proof of Delivery but can get no where with Verizon help. I was transferred 4 times and they still did not help me. Told me to call my credit card provider?? I do not pay my bill with a credit card! Can someone help??
