Sad service - even from AI

Very disappointed! At 8:43 on April 17, I received the first message on whattsapp that my parcel is out for delivery. I saw the address is incorrect. I tried to rectify it on whattsapp but a robot cannot respond to other messages as what is imported. I phoned customer care at 8:55 - holding for twenty minutes, then the guy assures me, they will phone me with the delivery. When I track my parcel, I was shocked to see that from April 13th, they say the parcel is undeliverable; nobody home; nobody answers the phone which is not true. I phoned customer care again at 15:34 and got hold of a lady that could change the address. I couldn't complain on their platforms, so I rely on hellopeter. This is really not good customer care!
