Access to Admin Features Locked

We’ve been having some trouble accessing our Admin functions and can’t find a displayed API Key in the place where we were instructed to find it on the Admin profile page. I work for a company who had an employee (who is no longer here) set up our website and WordPress account. We want to be able to add the stats app to our site along with getting our Admin power back.

The biggest problem is that we neither have the API number originally given or the original wordpress.com account UN and PW info. Pretty clueless I know but all the information that’s needed was lost with the departure of the employee who set it up.

I know it’s not a quick fix but where can I start to fix the problem?
