what can i do if my agency told me they cannot...

If your employer tells you not to renew your residence permit, in that case you can apply to transfer your sponsorship to another employer without the approval of your current sponsor.
And if there is any problem facing your current company that prevents it from renewing the residence permit, in that case your company must communicate with the General Directorate of Passports in order to solve that problem.
You can obtain contact information with the General Directorate of Passports through the unified national platform, by clicking on the following link:
