parcel due to be delivered to me on Feb 28 th or March 1st tracked as in in "local depot" on Feb 28th and disappeared.
They have NO interest in remedial action if they lose a parcel - it is up to the sender to make a claim.
This happened well before COVID 19 had any significant impact on courier services so not an excuse.
They exist solely because they are cheap.
DHL etc are more expensive not because they make more profits but because they have an effective and professional end to end logistic system . That costs money and that is what one is paying for: extremely high probability of delivery fulfillment
IF you want to make sure that your parcel actually gets DELIVERED then use almost any other courier e.g. Royal Mail, Parcel Force, DPD, DHL etc
