Poor Service

Worst experience ever, I have been double debited on my Dsl line and now on my mobile contracts I'm in arrears and the debit did not go off.. I have not been debited for mobile but my balance is over R2000 how is this possible??? I have a R1 spend limit set and my bill on the app was R856 I have money in my account to be debited but now my bill has gone to R2200 not on at all,Poor Customer Service as trying to call customer care cuts off, I just want my contracts to end soon and I'm Cancelling all my contacts.
