Wrongly debited

I was debited for my telkom account in August, even though I never recieved the phone yet, When we raised a complaint Audrey told us that the contract does not begin until the account is activated and that the Debit from August would be credited to our Bill when the contract is activated, even after bieng told this, we were debited for Sep and Oct however Sep's payment was debited in Aug as it was done before the phone was delivered.On 8 Sep 2015,who had advised us of the above, when I email her, we get no response to sort out this issue
