Express your issues in writing narrating issues and attaching relevant docs to your HoD and request to forward to the concerned authority for elections e.g; DC/SDM/Tehsildar.. Remain gentle and amiable.. Check if some committee is formed to address issues..!
Also meet all in person and also see if some replacement is also available..
This is what you can do.
Hope you had kept your HoD updated on exams that you are likely to take.
