My first real courier problem from Hermes recently.....'parcel not collected/unsuitable'. I bought a PA amp and the seller was very helpful all along.
Parcel WAS collected and a collection sticker applied by the Hermes driver as such, then 'lost' in the system of depots, apparently all because Hermes didn't put the large address sticker on, or possibly because the seller hadn't printed one off but that is for the Hermes agent to rectify at time of collection.
Luckily my seller had photographed all details on the box which were used as proof direct to Hermes. Zillions of emails and live chats, (no real person to contact, where IS the number?), threats of ombudsman and police involvement
finally led to my parcel being delivered safe and sound.
My lesson learnt....get photos whenever possible as proof and make sure everyone stickers the damn thing.....and insure!
