BYD Seal Hybrid Remote Access Not Working for Over a Month

I purchased a BYD Seal Hybrid, and for the past month, the remote access system has not worked at all. Every time I contact customer service, they just tell me to wait two days or to uninstall and reinstall the app—which I’ve done multiple times with no success.
I’ve called customer service repeatedly, visited the service center twice, and even had the latest software installed, yet the issue remains. The service center even emailed headquarters, but I still haven’t received a solution.
This morning, I called again, and all I got was, "We’ll report your complaint." I’m fed up with these empty responses! If BYD cares about its customers, they need to fix this now.
