I lost my reach account

A while ago I lost my XxHaloEpicxX account and in losing that I lost my reach account the rank it was when I lost was Major I tried really hard on that account and I’m wondering if anyone can tell if and if so how I can get it back

Define losing your account? If you can’t recover your Xbox live account then your reach ranks gone and there’s nothing to be done about it unfortunately.

You would need to know the login details (email / password) for that gamertag. If you can’t remember either one you may be able to recover it if you know information like security answers. Xbox Live / Microsoft Support would be best to contact

You need to contact Xbox support.
