Why bother having a customer contact centre landline or email....as all goes unanswered

I am waiting for a parcel which was sent from the UK on 09November. I understand that it will take some time, but trying to track it since it arrived in South Africa, is a hopeless case. The customer contact centre on ***is dreadful, as you simply don't get through to an operator. The following numbers which I was given, also just rings and rings off the hook ( ********** , ********** ). Nobody ever bothers to answer the phone. I have emailed customer contact support, and even though my email was read by a least once person (I added a read receipt when sending), not even that one person bothered to respond. Absolutely useless!
