Still no shortage of CIFAS threads on here I see...
To be honest, no, you will probably struggle to get any financial product for the next 6 years, it will be very tough. The two accounts that have just been purportedly opened will probably be closed within a few days, the CIFAS API check is not always done immediately and it is common to have them shut down shortly after opening.
There have been some cases of people's accounts (usually vulnerable people) being hacked/controlled by a third party and used to as mule accounts, but it's pretty easy for a bank to identify this from their internal investigation (i.e. different IPs/devices, locations being used to sign in). If you had reported it to the police immediately and received a crime reference number then there's a chance you could appeal against the marker if you were genuinely threatened, but that might not work anyway to be honest.
