I've a complaint that I've visited China Visa Application Service Center today on 12 February 2019. Which is located in 20/F Capital Centre, 151 Gloucester Rd, Wan Chai.
My complaint is that the women sitting in counter number 14 at the time of 3:30 P.M is very rude. She doesn't respect anyone. She even called a guy bloody foreigner which was really rude plus.
I would like you to order her to be polite and nice or else I will to take other legal actions.
