RIDICULOUSLY LATE

In February I was contacted by a male dealing with organising drop offs for UNISA students. We made an arrangement for the Tuesday between 8 and 12....I clearly stated that I needed to be contacted when they are at the gate. No one phoned, no delivery. 2 Weeks later I phone them to find out where my parcel is, then I am told by a young lady that all the waybills under my name has been delivered and that there is no waybill or package for this year. I explain to her the situation and she promises to phone back. Two weeks later. We are now in the month of March, I am contacted again. This was on the 12th, my first assighnment is due on the 13th. For delivery. I again state they need to phone me and this is URGENT since my assighnments are due and I still have not received any study material. She promises that it will be delivered in the morning and apoligises. NO DELIVERY. On Sunday the 15th at halfpast 12 I get a call from a delivery man. I tell him we are not home, they were suppose to have done the delivery on thev13th already and that they must bringbit the following day. TODAY THEY BROUGHT THE PACKAGE. I HAVE MISSED ALL MY DUE DATES DUE TO YOUR HORRIBLE SERVICE. WHO IS GONNA PAY
