Login error – Messenger Review

I used to loooove Facebook & messenger used to be one of my main ways of keeping in contact with old friends & family but over a month ago I was logged out of both my Facebook & messenger accounts, I've tried everything to log back in since including completely resetting my phone & even still I kept receiving the "unexpected login error" message. I've reported the problem SEVERAL times with no luck, it's gotten to the point I've completely given up on the apps & deleted them.
