My bill is usually 100$ a month. This month is 320. I went 2000 text messages over. My text plan is Unlimited In, 1500 out. I thought it meant unlimited received, 1500 sent. Apparently it means unlimited to Verizon carriers and 1500 limit for other carriers. I didnt know this. I called them up and they said that I cant change it because they already forgave me for a mistake I made previously. I was 500 messages over so they let me upgrade to a better plan to excuse the charges.

Is there anything I can do or say that will make them excuse the current charges?
