My boost auto recharge didn't happen when it was suppose to the other day either. Contacting them on their website is useless however if you contact Christine Lazona she gets onto things straight away. You can either email any problems at email@example.com or christine@ boost.com.au
When I lost all my data I just recharged with $20 and got 5G. I usually get the $30 one. Anyway they have manually transferred 20G over so I'm happy now. Hope this helps peoples!
