<human>: Condense the text into a few key points

I have a car loan in Australia through St George for $135(AUD) per week. This is a 5 year car/personal loan. I got it in 2013 so there are still a couple of years left. I am currently earning 21k (GBP) so I am more than capable to continue paying it off, especially with the exchange rate being so bad for Australia at the moment.

I am currently living in the UK and have been transferring money earned here to my Australian account to pay off my car. However it is a bit different due to being paid monthly here, I have to send monthly lump sums across. I thought this was up to date, but I just got a call from my parents to say that someone came to their house wanting to repossess the car. My dad just said he had no idea what they were talking about and closed the door, to be able to call me and let me know.

I just tried calling the St George financial hardship international number from [here] and got told they are closed (5:30pm AUS) even though the website says 8pm.. 

What are my options here? I hadn't received any letters about this, but the contact phone number was my old work phone for my job in Australia (because at the time I didn't think I'd be going anywhere, stupid huh..) so they may have tried to contact that with no success. If someone has already tried to take the car, does that mean it's going to happen, no matter what? I have money in an account here in the UK that I can send straight to them, and keep at least two weeks ahead, but I'm just worried that because it's reached this stage, there's no going back.

Thanks for any and all responses.
<bot>: Have car repayments in Australia, paying them from London, seems I have missed a few to the point of a re-possessor going to my parents place to take my car, what are my options?
