Sprint phone texting

ok, i have had a lot of problems with sprint texting this month… 100 dollars over this bill, there was a problem last month where texts were sending 4x and they would appear to NOT be sending, so id click resend, and then it would send another 4x… this caused me to go over by quite a bit, and its under investigation with sprint right now (thats what they told me… PITA) i should know more by thursday… but a bill that is 1000 messages over= not cool with me
