Faulty unit
Faulty unit, refused refund inside their own 30-day window Bought the Multimedia AI Box for BYD Shark 6 (Order #37351, $348.99, February 2026). Two faults from day one: a consistent 30-minute audio stutter, and GPS/network conflicts that made navigation unusable. I requested a refund on 23 March, 25 days after purchase — inside the 30-day money-back guarantee advertised on their own BYD Shark 6 product page. They never approved it, never declined it, and never provided an RMA number or return address. Instead I got two months of troubleshooting. I completed every step they asked. When they demanded videos of the fault before considering a refund, I supplied them. Their eventual "solution" was a video showing a BMW iDrive system — my vehicle is a BYD Shark 6, which I had stated repeatedly throughout. They then tried to move the conversation to WhatsApp on a +86 number, away from the email record. Their site promises "real-time personalised support" with a 12-hour response. In practice there was a two-week silence in April with no reply at all despite chasing. They trade as "Carlinkit Factory Australia" but the registered business address is in Changsha, Hunan and the contact number is +86. There is no Australian entity to hold accountable. Three months on I have no refund and no product that works.
