Our courier company destroy the your trust in us

I need to understand why Takealot has a dedicated line that deal with delivery's when it is a total waist of your time , I ordered an item , with delivery noted for today 24/03/2016 -then on Tuesday I phoned and spoke to Nancy Williams -Ref nr *** -requesting that the item must please be delivered before today 11H00 as I'm going away for the long weekend , today 11H00 the item was not delivered , phoned again spoke to a person in the delivery team that told me if i wanted to complain and can do it by phoning and choosing option 4 , I phoned again -spoke to a person who said they'll find out and give me feedback , I was then phoned by Zerelda Edim who then told me the person of delivery's did not have the right to make promises and also she then blamed Takealot for delivering the item late , she then had the audacity to tell me there is no driver now and I can go pick up the parcel from there Hatfield branch !!! Unbelievable, why is there a courier company if the clients have to go and pick up the parcel were it is dropped????? She then dropped the phone in my ear , Takealot this is what your courier company does with your clients
