That being said, i guess it never hurts to try.
Repeatedly emailing them does though... Keep opening support tickets and they'll be more likely to help. I did that with an exchange a few weeks ago, they took longer to reply so I went faster with my responses, got put through to an engineer who solved my issue in about 4 hours... Which is quite fast via email.
It won't work every time but its certainly not going to hurt by trying it if they doing give in on the first email, an email a day for 14 days gets to them.
