Worst Couriers, useless and unfunctional

I have been waiting for my delivery for 3days after it arrived 2 days ago. WhatsApp messages ignored for the entire 3 days and on day 4, an sms saying delivery could not be done it will be rearranged i should look out for an email. My parcel has been ready and shows at arrived at destination 5days ago, by the way parcel is at ORT Airport Kempton Park and i am just in Pretoria. What a useless courier
