My friend and I applied for PR together in Jan 2017; we both have the similar profile but he just got approved recently in Jul 2017, while mine is still pending

Our profile:
Malaysian
Chinese
24yo
Similar salary range
2 years of working experience in Singapore
The only difference is our employment history.
My friend has only one employer throughout the 2 years of working; while I have changed employers for 3 times (actually 2 times, please refer to the timeline below):
My Employment History:
Jul 2015 - Sep 2015 : Company A
Oct 2015 - Sep 2016 : Company B*
Oct 2016 - Present : Company C*
*Company B & C are related companies.
I was initially hired by Company B, but actually working in Company C office all the time. However a few months later, the directors of Company B & C had disputes and they decided to transfer my headcount to Company C & continue working in Company C. I also still got my bonus for Year 2016 from Company C.
Is this why ICA still pending my application for evaluation due to my job-hopping history?
I did nothing wrong about this... Hopefully ICA can look up in the Business Profiles of both Companies and found out that both of them are under the same directorship... I didn't highlight this in the PR application though... Maybe I should write them an email? Please advise.
Thank you.
