My questions now are:
- Will I ever be able to get a mortgage or bank account now with HSBC (or Halifax)?
- Am I black listed somewhere, if so, where?
- Who is there I can complain to?
- What if Santander do the same, and I can't get a bank account, how do I pay my mortgage, get paid my salary etc?

Scary stuff how the banks are so in control of our lives and can cut us off from civilisation by closing our bank accounts.
