No delivery or communication Pathetic service!!

I received two missed calls regarding my package that is sitting at customs for some reason. I cant understand why it would be delayed since it is valued at under R200 and are 10 sets of tested daily contact lenses. My tracking number is ***. I have repeatedly called the call centre and various area offices and yet nobody can explain to me what is going on. All they say is that they will get someone to call me. Its a week later! I want my package! I paid for priority shipping and this is unacceptable!!!! I want my package!!!!
