I am living in Hong Kong. I bought a Tommy Hilfiger polo shirt last month when I travelled to New York. When I was back to Hong Kong after three weeks of purchase, a hole was found in polo shirt. Then I send email to US Tommy Helpdesk. They said that exchange policy only apply to US. They suggested me to contact the local Tommy Hilfiger store.
Then I went to local store. They said that they don't have same model. What they can do is to fix the hole by needlework. I refused and email to US Tommy Helpdesk again. I emailed them twice but no reply so far.
In fact it is easy to solve my problem. E. g. refund via credit card, send the exchanged item to local store... But Tommy helpdesk just select to escape. And I have no way to escalate.
As a result, I would recommend all tourists to be careful when they bought Tommy Hilfiger in US.
