TERRIBLE CUSTOMER SERVICE AND NO HELP AT ALL

I get an sms this morning saying that my account has been debited of R708.50 but why??? My monthly contract fee is R608.50!!!! i call the call centre at 8:30 and waited 20 minutes before my call was answered by Ugudu something like that and she couldnt explain to me at all what had happened and when i spoke on she transferred me to the accounts departments. the best part is i spoke to zanele and while im speaking, i get a rate me survey. really? i rated u really bad because im fuming with anger. i then get a call but one miss call and again the call goes dead. pathetic staff and service. im going to report this because i want my money refunded bACK TO ME SEEING THAT NO ONE KNOWS WHATS HAPPENING.
