 * The program reads in the info and prints out in receipt form for the user who requests the
 *      information and gives a basic overview of where charges are made.
 * The program is for users who are on a basic $15/month plan including access Fees and emergency
 *      services costs
 * "T" Out oing text
 * "X" Incoming text (always free)
 * "I" Incoming call
 * "O" Outgoing call
