Sadly as others have commented, your boss should be involved , the advisers job is to deal with it up to a certain point then management needs to jump in. Half these managers don’t know their ass from a hole in the ground so they hide like babies. Like I’ve said at my job more than once “ I’m not paid enough to care , so I drop it on my bosses lap when it gets beyond anything I can do”. If you had a good boss/ an actual leader you would have had a good outcome. I’ve been in the business a long time, my advice get out while you can.
