Chubb - Random debit orders taken off my account

During the past two weeks three debit orders went off my account from Chubb. I'm meant to pay R 450 per month, but one debit order of R 900 went off, then one of R 560 then another of R 450. I called to ask for a statement but was told that because I'm on a debit order my statement will automatically show a zero. I said that its not a reason to not be able to send me a statement. That random amounts can not just be taken without notifying me as I did not factor these amounts into my budget. The consultant was not in any way helpful, she said she'll send it. I then had to ask her if she had my email address to send it to... she only then took it and said she would send it shortly. I have yet to receive it. <br> I have on a previous occasion requested (via their website) that monthly statements/invoices be sent to me via email, to which I still have not received a response.
