On 18 Nov 2020, when I travelled back to Singapore, one security officer named "FAROOK" was not quite friendly and professional when he conducted his check to me. After that I feedback this by submitting a feedback form to Changi and I received a response from Changi contact centre to clarify certain things. After I reply, it was quite some time they did not get back or update. When I sent an email to check, I was informed that they will reply within a week. However after that it has been 1.5 months that they never provided any updates though I sent a few emails to check in this period. So I am really not sure what and how Changi contact Centre is managing this.
