The attitude of Mr Li Ning from Delphin Singapore sales was terrible. He didn't bother to go through the delphin accessories at the point of sales.
What he said is just to ask me watch the u-tube video to operate the vacuum cleaner.
His after sales support is horrible. When I ask him what the plastic bag in the package is used for, his answer is that one no use one.
Review about: Delphin Singapore Sales Representative.
