Lost parcel. No delivery. No correspondence.

I cannot get my parcel which was sent from London on priority tracked shipping on the 27 September 2018. The parcel arrived in South Africa after two days and now it has been pending for a month with various incorrect reasons. I have repeatedly tried to get hold of Skynet telephonically and via e-mail. My calls keep getting cut off and I am given numbers to dial which do not exist as the systems are not linked. I have made well over 50 attempts to retrieve information on this parcel and I am still not coming right. This is possibly the worst service I have received from any company in South Africa.
