Rubbish customer service. I used Parcel monkey to deliver a package and they sub contracted it out to Parcel Force. Two weeks after it was delivered I was invoiced another £56 with them claiming that the package was over weight, yet on the invoice was an actual weight of 10kg which is well within limits. When challenged, the excess charge suddenly became because of a volumetric calculation - which is nonsense, you can't calculate weight based on just the size of the box. Again we challenged this, and then it was an overcharge based on a "girth plus length" measurement. Again this was challenged, but they just kept repeating it was my responsibility to prove it wasn't oversized. When pointed out that they took money from me and they should be proving it was a legitimate charge they just said that "the courier laser measured the package and he said it was too big". I asked for the print out to back up this claim and got the stock reply that it was my responsibility. I then wrote to their customer services and have been completely blanked, even though the letter was sent recorded delivery and signed for on receipt. Can't begin to describe how angry I am with them.
