Never answer anything

Got a parcel from Hong Kong. Contacted sapo only to tell me i need to phone international mail centre since it is there. Well it has been 3 days no answer from them. I dont have a south african tracking number. Poor service on behalf of them. Also e-mails and sms's nothing dead end. Truly the worst service ever. I have zero info on my package. Customer service that is non existent. I need feedback on the package. Beter to rather never get anything from over seas. Post service suck
