Questbridge Counselor Recommendation URGENT ISSUE

My counselor has submitted her recommendation letter and test report for my application. She needs to make changes, but was not able to do so. I have tried contacting Questbridge for weeks now through both emails and phone calls, but haven’t had a response. I can’t remove her and add her back again. Can someone please offer some advice on how I should handle this issue?

What kind of changes does your GC need to make?

She needs to make changes to the test report. I have tried removing and adding a new one, but wasn’t able to remove the report that was originally uploaded.
