Does anyone pay their Sprint Bill online? Its so frustrating because sometimes i think i paid twice in once month but it doesn't show. How can i check this? It gives out the information that you paid your bill but im pretty sure i paid my last months bill twice because when i veiwed bill it said "TOTAL DUE" like i haven't paid so i paid again but went back in my bank statement and it shows that i already paid the same bill. What do i do?
