Very late delivery

I sent a parcel from Kenya to Pretoria in January 2015. As to date, March 20 the parcel still reads \held by customs". I have been very patient trying to kindly ask what the problem is but to my suprise phone calls are not answered nor emails responded. I am very very dissapointed by the poor service. Please check my parcel RR***KE. And improve your services or else you will lose your customers."""
