I placed an order with Hattons recently and they shipped it with DPD. DPD then stated they couldn't find my address day after day despite me taking time off work to make sure I could be in all day.
Rang up Hattons and explained the situation and they agreed to recall the parcel and ship a replacement out using an alternative courier which found my address no problem. I felt this was a satisfactory solution.
I may also add that contacting DPD is an absolute nightmare as they don't have a telephone number for their depots/drivers so it is up to Hattons to get in contact with them.
