Double billed me again. – Bridge to Another World: The Others HD - A Hidden Object Adventure (Full) Review

I downloaded this and paid $6.99 plus tax, confirming billing sent on 11/15/15. I downloaded it today and 'no purchase found'. You owe me a full refund. This has happened several times. What dies 'own for life' mean?
