No customer service at all, rude and unprofessional

I did click and collect, my worst nightmare. I went to collect my parcel and a guy called " cash" he refuse to give his real name, said he could not find it. He will check the next morning. Around 11:00 am I called they said he is out they will tell him. I called customer care the parcel is there. He then called me so rude and told me he went to the childs school ealier, I was suppose to wait for his call not to call customer service. When I said its very time consuming to go all the way back there. He said "Hay suka do whatever you want" and drop the phone on my ear.
