SA Post Office lies

On the 8th February I posted a parcel at Meyerdal Post Office, destination Belarus. I was charged over R900.00 because delivery was sort of urgent and I was told that it would take between 10 to 15 working days. The moment I got the tracking number I started tracking the movement. The parcel was collected the next day 9th February and went to Witspos. According to Meyersdal Postmaster the parcel should have never gone that route. I’ve been calling on a daily basis the Post Office Customer Service and Post Office Meyersdal but no one can give me an answer as to what happen to the parcel or where the parcel is. I decided to write and email to Mr Mark Barnes, Post Office CEO, but that was in vain as well. I demand to know the whereabouts of my parcel and would like a full refund of the money paid for non existing service. It is the 14th working day from date of postage and the parcel is still in South Africa.
