charges

I called telkom /8ta when my contract started after I was billed before our agreed date,they explained they had to debit early to activate my account.The bank charged me R115 for not honouring that debit order. They debited my account again early on the 24\11\17 and i did not have sufficient funds in my account,I was charged again R115...I called their call centre and I was told thers nothing they can do did I not read the terms and conditions.I then asked her to log a complain for me,she told me she can't,I asked for the internal arbitrator s number she said they don't have...I asked her to escalate this matter to her team leader and I was promised a call within 24 to 48hrs,no one called me ….I want 8ta to refund that charge and to stop debiting my account early... My contract number is ********** 426
