Tracker over billing

I am applauded by the service that I am receiving from tracker. They doubled billed me in May and it was struggle to get a refund. I had to continuously phone the Tracker Network Pty.LTD Call Centre. On the 1 August I was triple billed and I phoned the call centre twice on the 2 August for an explanation and they could not give me one. I was assured that a supervisor will contact and I will be refunded. I received no call. On the 3 August 2023, I contacted the Tracker call centre and requested to speak to a supervisor. The supervisor had no idea of my challenge and nothing was done by the previous supervisor. The supervisor that I spoke to today assured me that she will rectify the problem and a refund will be made today. It is disappointing that one is continuously put on hold and has to struggle to get your money back.
