poor service

my parcel has been out on delivery since last week Thursday but I have not received the parcel they keep saying I was not available but noone bothered to call and theres always someone at my address 24/7. I've been trying to call the last depo (Richardbay) to find out the problem but they keep saying they will get back to me. I've sent countless emails Noone responds. I just want to know where my parcel is so that I can go fetch it myswlf if the company doesn't want to deliver. Its way overdue and I have very urgent items inside
