It's interesting that you point that out, I'll probably contact my bank about it tomorrow.
This isn't the place for discussion of my personal credit record, but it may be interesting for someone. I had a charge of 237 GBP on 11th April (the one that pushed the balance into debit at all), and the bill on 12th April, with a due date of 11th May (according to the credit card website). The next payment was when I noticed (thought) it had been missed - but was on the 10th of May, 1000GBP pushing the account a few hundred back into credit (i.e. negative balance). So judging by what appears on their website, it was actually before the due date. Yet it showed up in a credit report (Experian's creditexpert.co.uk free trial)...
