Undelivered permit
I was in Colombia and decided to have delivered both digital and physical formate of the permit whose cost was about 30 euros. That was 6-7 weeks prior to my planed trip. I received the digital one quite quickly but the physical one never came. The company was assuring me last 2-3 weeks prior to my trip that it was on its way. Turned out that the company had no clue where the document was since they had sent it via a normal post with no tracking number. I asked for some partial refund since I am not responsible for this uncompleted service. After some longer discussion it was offered to me 5 euros.
