Yes could be! I’m in the south west and DPD has been terrible here for a while. A year or two ago they were by far the best.
They really show themselves up when anything goes wrong and their customer service is non existent, or rude at best.
I agree about myHermes - definitely an even worse option.
Around here, Yodel are better and much cheaper too. They text you first thing in the morning (unlike DPD who text you at midday IF their tracking system is working which is hasn’t been for weeks), and rather than give you a time slot they give you the drivers phone number. Text the driver and they are amazing - polite, helpful and flexible. They’ll actually give you a time that suits you if you ask. And they pretty much always live locally and are happy to drop your parcel at lunchtime or in the evening. REAL customer service.
Options are limited I know, but if companies don’t threaten to remove their custom, then DPD have no incentive to improve as the only person who loses out is the end buyer who often doesn’t get a choice of who delivers their parcel, and are powerless to complain or get compensation as DPD hasn’t been contracted by them.
