DOUBLE DEBIT AND BANK CHANRGES

My complaint is for mobile number *** that I called in and was advise to pay cash as the debit will not go off my new bank acc details. I paid cash but despite this you have debited my account R458.00 There was insufficient funds on my account and now a further R200 charge is on my account. I have attempted to call for an entire week and have requested a call back on *** but not one person has assisted or contacted. I am wanting a full refund of MY MONEY INCLUDING MY BANK CHARGES IMMEDIATELY. Honestly this is the most PATHETIC SERVICE ever received and I am disappointed especially being a fairly new customer with this network. Can somebody please attend to this matter urgently and contact me with an update. Acc number for telkom contract ***
