It has been dropped in recent months to be honest. I think because of the cost cutting, they have hired less experience people.
They make a lot of spelling mistakes and they talk in a very improper manner.

So I am guessing that the customer support manpower of India (which is highly rated) is being used for the newly launched Amazon Singapore.
