Evri complaint: Courier fault

Hi,
The issue it’s start with one big order who was packed and send it in 3 parcels,the courier (Leon) who thinks is smart did scan 3 parcels but the biggest and most expensive he didn’t deliver it but just the other 2..next days coming for the other delivery i asked him about the parcel and he said didn’t know anything…so how could be someone so liar and thief and in the same time to work for a “big” delivery company ..??we have the proof that he didn’t deliver all the parcels as he took a photo of my son and to the door not to the parcels..I will attach some photos where can be seen the all 3 parcels out and “being “ delivered to I don’t know who..but not to me..
Than the courier (Leon) gets upset still after all this and he start to play more smart and to lie more and more..
As the next days I still have parcels he start to not come for delivery at all and to put in the system that I’m not home this being not true..I was at home every time waiting for the parcel and wasting my time..
I’m asking just how we can get justice when some pricks like this are playing with the people thinking that they are untouchable…
