Evri, the courier firm formerly known as Hermes, has been ranked as worst for service for a second year running by Citizens Advice.
German-based Evri was rated an average 1.75 out of 5 in the 2022 parcels league table by the consumer advice service.
Royal Mail topped the league with a 3-star ranking and beat Evri in every category including trust and problem-solving, though it is more expensive.
Amazon Logistics, DPD and Yodel all failed to achieve higher than a 3-star rating.
DPD the most expensive deliverer scored 2.25 stars enough only for third place.
Yodel achieved the worst single rating of 1.7 stars for customer service yet avoided the bottom spot with an overall rating of 2.
Not a single company is offering 4- or 5-star service with Royal Mail having 4 of their rankings achieve 3 or higher.
Consumers have highlighted disappointment across all parcel firms with calls for Ofcom to introduce fines for failing consumers after 64% said they had had an issue with deliveries.
An Ofcom spokesperson stated “some parcel companies are failing their customers when deliveries go wrong. So, we’re strengthening our regulations next year to make sure people are treated fairly by parcel firms.”
Yodel responded: "We disagree with the methodology and findings of this report. Our own parcel data and Have Your Say feedback programmes show that 84% of our customers had a positive experience with us over the last six months.”
An Evri spokeswoman added: "Evri delivers over two million parcels each day and we pride ourselves on offering a fast, reliable, sustainable service which doesn’t cost the earth for consumers and businesses alike."
