Literally 'bad luck' but used in Glasgow, Scotland, more like the American, whatever
1) your situation is unfortunate, but none of my concern.
2) your predicament is indeed sad, but outside of my control and therefore nothing to do with me.

4) While you may have a case for compensation you have no evidence to support your claim.
