A BACKLOG of undelivered parcels is piled up in Holmfirth sorting offices, it is alleged.
A Honley man who says his parcels were delayed two weeks wants answers from the Royal Mail.
The complaints come after months of postal problems in the Holme Valley following the introduction of a one delivery a day system.
Earlier this month, Kirklees members of the Mid Yorkshire Chamber of Commerce quizzed the Royal Mail over the changes, complaining about late mail.
In this latest complaint Honley man Steve White said he had waited more than two weeks for some vehicle manuals he ordered to arrive.
He claims when he called at the Holmfirth sorting office he was told his parcel was in a heap of undelivered parcels too large or heavy for the walked delivery.
After his complaint Mr White, of Croft Drive, said his parcel was delivered within the hour.
"Shouldn't someone at Royal Mail be held responsible for the new Performance System?" he said.
A spokesman from Royal Mail blamed staff sickness for the problems, which he claimed were exaggerated.
"We are experiencing unusually high sickness levels among our Holmfirth staff," he said.
"This has resulted in some problems particularly with parcel deliveries but none have been delayed for anything like two weeks.
"We have taken on casual staff and parcel deliveries are back on track, but we apologise to any customers who have been affected."
