All my accounts were shut down when TSB labelled me a ‘fraudster’ instead of the victim

I have been very badly treated by TSB, even though I have never been a customer. It mistakenly placed three fraud markers against my name, which prompted my bank, Santander, to close all five of the accounts I held with it. This has caused significant financial problems since direct debits and standing orders failed, and I was unable to start a planned house extension. TSB has not responded to emails and letters since this happened eight months ago.

I have complained to the Financial Ombudsman Service, but because I am not a TSB customer, it can’t investigate.
