Verizon

I have had service with verizon for a while now I have come on some hard times so I am low late with my phone payment i was given no warning about my phone being turned off when i tried to make a call to my doctor i was directed to Verizon for payment which i did not have at that moment but was willing to make some kind of arrangements i was demanded by the rep to make a payment that day . I am very disappointed in Verizon i needed to speak with my doctor for test results and could not make a call . I would like to cancel my service and return the phone and would like someone to mail me a return slip asap. Thank you Dawn Martin
