UPS Irresponsive

This now the second time my parcel has been in the UPS Kempton Park warehouse for more than 5 days. I sent numerous emails inquiring on the status of customs clearance and when my parcel will be shipped to my delivery address. I get absolutely no response on my emails and reading other reviews I am not even going to try and call them. UPS does not come near their competitors they are slow and useless.
