Evri complaint: Delivery not received

My parcel stated delivered on the 10th, no parcel.
Ut also stated delivered to my safe place the back door, this is not my safe place and not easily accessible for a delivery.
Called sender and they have advised that he has got to speak to evri and they have said there is an error with my delivery , it was not delivered ??? Well I had no photo of delivery for a start anyway and there was no card put through to door to re arrange either.
U have tried to contact evri since and the number just states technical difficulties and goes dead.
I am absolutely furious and avoid evri usually at all costs when ordering items.
This time I didnt check the delivery co.pany and with I had as would have gone else were for my parcel.
They are a rouge company that has zero customer service and employs people that can not seem to do the simple tasks of their job, with zero repercussions for their actions.
Evri ,hermes, what ever you want to call it is a absolute shambles, a business that should be closed down and investigated including dodgy delivery drivers for missing parcels, which I have also experienced in the past and is why I avoid them.
