I made four complaints so far, through online as well as telephone hotlines. You know what, this is their standard answers:
Dear Mr Tan,
Thank you for your email to so-and-so.
We are sorry that you have not been treated well at the outlet counter at so-and-so. We will look into it and we assure you that this would not be happen again.
Should you require any further assistance or would like to submit any enquiry/feedback, kindly visit bla-bla-bla and click on Customer Support.
Mr. Tan, we thank you for taking the time to write to us and look forward to serve you better.
Customer Care Support.
What a LP-PL answer they have. After this email, they consider this case solved and closed. And we as a customer, are forced to accept such a ridigulous answer and consider it resolved. What the f***!!
