Just cannot deal

This is not a courier company at all and will not be referring them to clients or suppliers.Just spent 45 minutes and so many calls on hold, only to be cut off so many times without customer services even answering,I have called from the Durban branch to JHB.Whilst on hold and while they trying to find out why my package was not delivered yesterday . Their reception insists they have no telephone problems, so what conclusion am I to reach about this issue? At this stage,i am highly irritated as their tracking system says theres no way to contact me and i have not been contacted. Fed up
