I had COVID earlier in the year and used vacation time to be out for a week. When I came back I was informed by HR that we have COVID time and she wanted me to send quite a few things in so that she could change the time over to COVID time and I would get my vacation time back. I called about this later because my vacation time wasn't back and she admitted (on the phone) that she had forgotten to change it and she would do it that week. Now it's 3 weeks later and I've sent two emails and she won't answer me and still hasn't changed it. I sent another email today and then I went and found her boss's number and left him a message. Is there anything else I can/should be doing?
