International parcel delivered to the wrong post office not willing to relocate

Hi Have been trying to get hold of a person at the national call centre, I wait for hours on for an agent, i spoke to an agent eugine, she first said that the tracking number i gave her cannot be found, i then emailed her the slip, awaiting reply, 3 days has passed no reply to email, the post office has delivered the parcel to the wrong post office which is half an hour away, i have queried for them to relocate the parcel to the nearest post office, i then phone again waiting for hours trying to get hold of her, the excuse is that i cannot get hold of you and we cannot till cellphone numbers out, she then tells me that i need to go to the post office my self which is half an hour away from me to fetch the parcel they cannot relocate it, i then told her please put me thru the manager and 10min there no answer call get cut
