I've used my TracFone for 3 years and never had any problems. I currently have over 722.5 minutes and a contract date which allows me to have the number until 10/28/09. I was so happy with my TracFone prepaid service and suddenly, my phone number was no longer in service. I had done nothing but buy over $135.00 worth airtime in May '07 and suddenly, my phone number was no longer active. After spending over 3 hours on the phone with TracFone, they claimed there was nothing they could do for me. I considered this a breach of contract and was out of cell phone service and money.
