How to change iqama profession and renew my iqama?

Hi guy's I am Shahzad Ghafoor. Living in Jeddah, Saudi Arabia. I am working as an IT Technician in software base company from 4 years. I have intermediate (F.A) qualification. and I'm Microsoft Certified IT Professional (MCITP). But my iqama profession is still "Building Technician" which is from first day. So problem is here now my iqama is expired and I want to renew it. But its not going to renew until I change my profession from "Building Technician to IT Technician". I handover my MCITP certificate to my kafeel. But profession is still "Building Technician". I am just worried about my iqama. Please give me suggestion what I should do to change profession and renew iqama.

Sorry for long description.

Best wishes
