I've spoken with support again. The ticket ID that you posted above was responded to within 24 hours by sales, so if you did not get it, it was most likely trapped by your anti-spam.
Unfortunately as you gave false details on your account, support was unable to check the status of your previous tickets (though I expect they were similarly replied and spamwalled) or seek the information they needed to solve the issue without further input.
Typically the issue you encountered is simply due to having bought with paypal, while using different email addresses for Impulse and paypal. If you provide all of the details to support (Order number, paypal email, impulse/sins email) they should be able to merge the accounts immediately upon receipt of the information (so any subsequent spamwalling of their replies shouldn't matter).
