Help With selecting NOC Code - Marketing

Hello all i need help with selecting my NOC Code.

I have exactly 3 years work experience at an entertainment company. I was hired as a marketing manager and then after 1.5 years i was promoted to Head of Marketing at the same company. My question is that can i claim the max 3 years points for this job as i am still working here ? i dont want to show any other job in my work experience . also , i have a masters in marketing degree aswell in my ECA report.

i am selecting the NOC 0124 Advertising, marketing and public relations managers and showing all this experience under same NOC. is it ok? is this the correct NOC for me ? need help and advise … thanks
