Trouble Logging In to WordPress

I work for a company known as Seco South. The website for the company is hosted on GoDaddy through cPanel. Prior to my being hired, the website was largely neglected because there was no one employed to take care of the website. During that time, the login credentials were lost. The last employee to work on it left the company on bad terms (as I understand it), and I attempted to reach out to him to recover the login credentials to no avail.

I have tried a few different things like password resetting with the email addresses that should have been associated with the site as user logins, but despite the back-end information I’m given through cPanel this hasn’t worked. I have attempted to go through cPanel by changing the passwords and to add myself as a user, but neither of those have been the solution.

As a bit of information, WordPress is neither installed on GoDaddy nor cPanel so that seems very odd to me and that there’s a possibility that the former employee who left on bad terms may have sabotaged the website itself, but maybe I’m jumping to conclusions. My supervisor would prefer for me not to install a separate WordPress, but with each day that passes, it looks more and more as if that’s the best solution especially with all of the former users being on old (seemingly non-existent) WordPress.

Any information of how I can proceed forward would be very much appreciated.

NOTE: I am using Windows 10 and Microsoft Edge on my work computer.
