When you buy something and are sent the wrong item. Always seems a lot of effort to put right someone else's mistake.
Worse when they make a mistake but then try to make out you're lying. I ordered a new groupset from Merlin and it was missing the front mech. I informed them as soon as I'd opened the packaging and checked the content. They then insisted I take a photo of it with the packaging to 'prove' it was missing. If I'd really wanted to rip them off all I would have had to do was exclude the part from the photo so it didn't prove anything, just added a layer of hassle and annoyance at effectively being accused of lying. I would also have claimed it was one of the higher value items missing.
