Neotel not answering my E-mails

I have previously complained on Hello Peter regarding all my Queries being ignored by Neotel. My contract was breached by Neotel, lots of times. I have contacted Neotel via Phone & E-mails to no avail. I have been double debited many times. My Capitec Bank account is now damaged due to Neotel debits..Neotel has been charging me: R97 for un-paid debits....I have proof as in Bank Statements that monies were in the bank for all my debits, but Neotel says otherwise. On 30-01-2016, i had deposited R400 into my Capitec Bank account to cover my debit from Neotel for:R226 + R97 for un-Paid Charges...But Neotel never took off their Debits on: 1st. Until the 7th monies were in the bank. Suddenly yesterday i received a call from their center that monies were not paid for the debit. My bank says otherwise. Proof can be made available to you. Neotel is now abusing my Bank account...Neotel's statement to me show another amount, and they ask for a different amount..This has been going on for +- 2 x Years. What do i do now? Account dept are very rude to me. People i have spoken to: Onnica Ledwaba/Lwazi Zwane/Lindiwe/Mmabadisa Mokoena/Mnamy Khosana. They cannot help me in accounts.
