I have today received a letter from Ing Bank (recorded delivery) which from google translate would appear to be offering some sort of investment, as I don't have an Ing account I am suspicious, although many years ago I had an Oyak bank account which I think was taken over by Ing. I find it hard to believe that they would write to offer investments and send it recorded delivery when, if it is still valid, there is £20 in my account. Has anyone else had this letter? Strangely there appears to be no return contact details.
