I have had this happen to me, been in all day, then receive an email that Evri tried to deliver / attempted delivery made , at such and such a time. Absolutely not, no one came, no door bell rung !
Same delivery driver came next day so I asked him. He had tried to deliver but ( we live on a one track road) a removal van was blocking the road and he couldn't pass, they have limited reasons to select for a ' non delivery' , and if within a certain distance, their choice is ' attempted delivery'.
Not ideal I agree, does not explain the situation accurately, but I was offered in the email, an alternative for the delivery I selected next day, and all was well.
