They are listed as ProTech Appliance Service Center and (are/were) located at South Road Calindagan (near Ceres Bus terminal as seen on google maps) with Phone Numbers (035) 422-2841 and 225-1029. I cannot seem to locate them and they do not answer the phone numbers listed (called from my cell phone). My question is does anyone know where they are or have relocated to and how to contact them as they appear to be the only Authorized service center for 3D appliances I was able to locate in Dumaguete. Or is there possibly another service center I am as of yet unfamiliar with? Please help. Thanks in advance! DaveD
