Good afternoon. I can bring sincere sympathy, because this is a significant breakdown of the doors and it is good that no one was injured!. I throw you a link to an article about replacing the door cable https://www.markodoor.com/garage-door-cable-repair there you will find all the information there. But it is better to call immediately on the indicated phones and call the master. The main thing is not to do anything before the arrival of the masters. These guys will definitely cope with any kind of work - the springs were changed to us and the impression was left only the best!
