Cannot delete service key

How do i recover from here?

Failed to delete the service key. 

Service broker failed to delete service binding for instance <service id>: 

Service broker error: Service broker hana-broker failed with:

i may have confused number4 with number3, etc but the service instance name is assigned by me: 201221svc
