Mag box issue

[RookieIP]

Hello everyone, I'm still new to this IPtv things. Here's the story and issue I'm having, few months ago i bought a box with service for a website called "https://xxxxxxxxxxxx.com" and the service ended up shutting down. Now I'm in the process of looking for new service, but using the same box. Only thing is i ran into one company which they emailed me back saying that my mac address subscriber panel is currently blocked. The only way they can activate the service is to get the mac address released from the old subscriber. Well i try to email the old subscriber, but no one is emailing me back, so how can i go around this are release my mac address or change the mac address if possible.

please help me


Box name: Global Media Box 4K
