I don't receive statements

I have an account with Hi-Fi Corporation. It seems I haven't received a statement since September 2017. It also seems that my installment gets increased from time to time without my knowledge. I called JD Group's call centre in my lunch break. I held the line for nearly 10 minutes. A lady picked up, I told her that I don't receive statements and if she could help me with that as I want to settle my account. She said she couldn't and would give me a number. I told her that I can't take the number as I did not have pen and paper with me, I was sitting in my car. She then put me through to the correct department. However, a message played saying I should enter a valid cell number or something like that. I then ended the call as my half an hour lunch break was over. I am writing here as it's nearly impossible to speak to a call agent and I also previously sent an email inquiry to the email address on the statement but never got a response. Please urgently send me my latest statement, settlement amount and banking details so that I can settle my account. Thanks
