Yeah it was delivered weeks ago and received the surcharge bill last week which made it much more likely for the packaging to be thrown away. I definitely measured and input the correct size but the parcel agents are saying that I dont have proof of its size so without photographic evidence DHL wins! Theyve already been billed by DHL so say they are passing it on to me. I quote from the agents:
"As I advised, we cannot dispute this with DHL without proof, I have given the details of the order was sent without any issue but unfortunately they do not deem this as sufficient evidence to overturn the charges.
If you can provide photographs as mentioned previously I can dispute this further, unfortunately if these are not available I have to uphold the charges incurred & request that these are paid."
I've contacted DHL directly and hope to hear something from them soon. If they insist my parcel was the size they claim (2.5 times its actual thickness, 1.5 times its actual width and 8cm longer) then I want photographic proof that it was my parcel!

I also want the paperwork that ties the DHL tracking code definitively with the websites order number and where it was scanned. That kind of thing...
This all seems so wrong there must be something I can do. I cant think straight and feel I'm missing something obvious but the payment reminders keep coming and winding me up.
