On its website, InPost UK blamed the problems on a “software integration issue”.
It said it had “isolated the root cause” and was “making significant progress” on resolving the problem.
However, some InPost UK users were told the issues would be resolved by Wednesday but have been left waiting for their parcels.
Posting on X, one woman described, external how she was given a new delivery date for 22 October, adding she “won’t use Inpost ever again”.
Another posted, external: “Here we all still are in the dark about where are parcels are and when they will arrive.”
InPost acquired parcel delivery firm Yodel in May, a move that the two companies said would create one of the largest logistics firms in the UK.
At the time of the deal, InPost UK chief executive Neil Kuschel announced plans to expand and handle more than 300 million parcels a year, saying the company was “reshaping the future of parcel delivery”.
