Thank you for making enquiries regarding after sales service. I am Mrs Theresa lee, had your company installed window film through Andy Foo about one and half months ago. I had my balcony and study room laminated with Neutral (scratch resistant) WCXAN20NSRPS and I am satisfied with the results. My  purpose of installing the film was to get rid of the glare and it did just that. Thank you. Best Regards.
