I don't like Hermes (but I like DPD).
I was waiting for a parcel when I started receiving contradictory emails from Hermes. One said the delivery would take place in a certain timeslot. One said it was postponed until the next day. One said the delivery had taken place. I phoned Hermes. They said they would get the local manager to contact me.
Next thing the delivery driver phoned to say he was here (in his van that is, when I live in a top floor flat). I asked why I had been given wrong information and he became hostile, asking if I wanted my parcel or not. I went down to collect it. He said it was nothing to do with him as he did not work for Hermes. He said he had been round earlier and no-one was in (untrue) but he was unable to tell me which flat he had been to. Finally he said I could complain about him if I wanted but it would achieve 'f*ck all'.
