Unsatisfied Vodacom Customer

Vodacom, are the biggest ******* , they recently had a special which I have taken at the rate of R349 a month but for the first debit they charged me R1400 and when i queried they insisted that the contract i have take costs Approximately R650, I've been waiting over a month for them to credit my account from the double charge and still haven't gotten my money which is completely ridiculous , when I reversed the debit order they phoned me up and threatened me that they could make my credited rating bad( make my name bad) please could someone higher than customer care contact me and help resolve this issues as the call centres is utterly useless, seriously regret getting a contract with Vodacom i would not recommend it!!!!!
