When wise ran a KYC, we had quite the confusing back and forth. The only documents I had which they nearly liked were from HMRC - but they didn't like that they were > 1year old.
In the end I rang HMRC and asked for any paper document they could send me with their logo, my company name, my trading address and my registered address on it... the lovely HMRC rep worked out which real document I could trigger. A complete waste of her time obviously.
