Delivered package was badly damaged - Consumer Complaint for LBC - Head Office

I would like to file a complaint regarding the package I sent last June 18. The package contained a bicycle helmet that was declared Php500 worth. The consignee is Bon Cecilio A. Academia, and his address is blk 9 lot 8 Silliman Heights, Junob Dumaguete City. He got the package but received it badly damaged. I chose LBC because I have high expectations with this company. For this matter, I would like your good office to investigate this incident so I can fairly claim whatever I am legally entitled with. Thank you!
