Well normally I have had a surcharge nearly every month for a weight issue on just one item, always just the one item, once a month.
But the last two items I have had it where they have told me the packaging format is incorrect where it should have been a package rather than a large letter, I told royalmail that when the item left me, it was a large letter and showed them proof of what was in the envelope, what the customer purchased and also showed them that it could fit through my Royalmail sizes template thing that I use to check that my sizes follow their guidelines. But as I use bubblewrap envelopes, as it is a C sized envelope although my item is less than 2.5cm thick, they told me that if the outer packaging can change shape as it's not stuck to the item good enough, then how it lands on their weighing conveyor belt is how it gets measured no matter if the item was mishandled or squashed up during being in their hands due to how it's handled in sacks or under other customers packages, so they basically told me that if I package items in bubblewrap envelopes and the envelope changes shape due to another parcel that may squash that envelope while in their hands, it's still a surcharge being given to me and an incorrect weight change. This is absolutely fraudulent and disgusting, they also said if air gets into the envelope so it's slightly blown up even though if they just gently squashed it down by their hands easily without any force, that would still be considered as a package rather than a large letter no matter if your item in the packaging is only 1mm thick or 2.5mm thick. I know that the way Royalmail handles customers mail, they stack sacks on top of each other, large letters will get squashed and chagne shape all the time while in their hands, but we are the ones that then get penalised for it. I was directly told something along them lines by a employee when I tried to get the surcharged waived and then I complained when it was rejected.
