Maybe you sent an email or something? There is only 1 case ever for your userid or email address. We only do support via the support system.
When you submit a case it gives you a confirmation and case #. Do you have that for either of your other 2 support cases.
The only other thing that could have happened is you clicked to submit the support case but it failed in which case it would give you a failure message rather than a support case #.
In any event we answer all support cases with support #'s. We can't answer support cases that aren't in the system.
