Went once and keep getting phone calls and letters from third party companies asking if I need assistance, I have medical insurance and have not once been contact by cox and I do not need assistance with anything. Very unprofessional and I have lost all respect for this company, I have tried contacting them multiple times and its never the right time or phone number for them. They do not care about their patients and show no respect once you leave their building.
