Candy Crush Soda Saga, Game #1221.

Saturday, didn't have enough gold bars to purchase 5 moves, so bought them, only received 3 moves.  Was going to let you know, but decided it was no big deal.  A few minutes ago, I used some of the last gold bars to buy more moves...ONLY RECEIVED 3 MOVES AGAIN! And I didn't complete the game...again!  Why does this happen? this is a hard level, at least for me...(I'm old!)
