Lost Access rights of Project directory

Dear Members,
One of my colleague created a repository for a project on code.company.com and assign me the developer rights with a specific target date to access that repository.
Now that colleague left the organisation before few months and that access rights target date assigned to me is expired which results now that project is not visible to me in my project list on code.company.com.
How can I get access of that project again and get back to business?
Please suggest needful. Thank you.
