Interpreting HSBC's silence

When you are faced with what amounts to silence from all the HSBC staff you talk to, your only option is to imagine explanations. Why has HSBC decided to close my account?

Because I travel frequently to Africa?

Because my account goes relatively quiet whenever I'm abroad, then wakes up again when I'm back in the UK?

Because I have bank accounts in France and Togo?

Because most of my income is in the form of donations given through a UK registered charity?

Because I've been paying in a lot of cash from car boot sale fund-raising events recently?

Because I used my debit card at an Arab restaurant in Jerusalem last week?

Who knows? No idea at all. Your guess is as good as mine.
