Silverlakes manager and staff hostile and unhelpful

The service at Postnet Silverlakes is bad. Staff is hostile. When I told the manager, he was equally hostile and justified their poor service.

They did not update waybill info online and when I called, the woman who answered said my parcel is not there. I went there and a man asked me how big is my parcel, instead of checking the waybill nr.

The manager said they don't contact clients when they get a parcel but they seem to have not recorded it either and it was there for a week. Online it did not say that they have it.
