no local reference number for parcels

i am not happy about the service i received at the post office in ruimsig as i am expecting international parcels from the US and wanted them to give me the domestic tracking numbers unlike before when they used to call the call centre and get the tracking numbers for me. i dont know what has changed since before that made it impossible for them to call customs as i do not have time as i work from monday to saturday and do not have time to call the call centre. i was told to send my tracking numbers to [Email Removed] but eversince i havent gotten any response as yet. i am very dissappointed
