Tracfone Lost minutes Nationwide

I had over 2700 minutes added back 4 months ago. This should last well over 18 months plus. I only call home when I'm out of work to see if  they need anything in town. Sometimes only 20 seconds at a time. I had 2600 minutes on this phone yesterday. I went to call home and I didn't have enough airtime. I looked and it was less then a minute on the phone. I called to see where all my min. went. They see no record of me having them. WTF. I said. They couldn't see anything. They said I must of used them up. I said if you don't see anytime left in the past few days how did I use them? could wouldn't help me at all even after speaking with four diff. people. I don't know what to do but to let you all know. They said I could add time. I said why so you can "STEAL THEM FROM AGAIN AND SAY I DON'T SEE ANY RECORD OF THEM"
