Well. Too late. Now that they go you want to talk? If I was the one who finally had enough why the fuck would I want to talk to something I turned my back to?

There were very clear statements of what will happen and why. First acknowledge those, express you are sorry for what happened and hint some mea culpa and how you plan to solve it.

Only then if you feel the need to talk realize that you are the one begging them, not the other way around.
