Meta Quest 3S Won't Charge – Intermittent USB-C Connection Issues

I purchased a Meta Quest 3s 3 weeks ago. It was working fine until 2 days ago.

When I plug it into the provided USB-C charger, it connects and disconnects intermittently. Initially, it struggled to maintain a stable connection for about an hour before it finally began charging. After my next use, the battery drained completely, and now it won’t charge at all. Occasionally, it briefly makes contact, but it immediately disconnects again.

It's been 40 minutes and it isn't charging. I've tried multiple adapters, cables and outlets.

I'm in Argentina, and Meta Support say they can't send replacements.

Any idea how I could go about fixing it?

Thank you!
