I was offered by Catawiki in a relatively low price of an 18k white gold diamond pendant in devil teddy bear shape. I confirmed my purchase at 6:23pm (11:23 CET) of 6 January 2021. The deadline for such was 21:13 (CET) of 8 January 2021. Since I found I could not pay, I informed Catawiki at once, on 6 January 2021. Proof from my attached picture/s. Catawiki blamed me that I missed the deadline. They adduced no evidence to support their allegation. However, last time I found that even after paying for the winning lot, they didn't post it to me but had the same item resell on auction in the following Friday. There was an intended purchaser who won in a higher price. I am Whether it was the real reason for not posting to me? This time, they alleged with no evidence that I missed the deadline and refused to sell me.
