I would give them a zero and never deal with them again. I went a year without receiving a bill and every time I would call them they would tell me they could not find me. When they finally found me they wanted me to pay a years worth of payments at once. They charged me 50cents extra to send my bill in the mail and I never received them. I had to call them every other month. I called and wanted and updated system and a salesperson never returned my phone calls or showed up.
