I uninstalled the BitDefender software exactly one day after I purchased it, due to the 'not so publicised' compatibility issue with the PunkBuster software. The only advice I was given at the time was to uninstall PunkBuster, which being a core component of many of the latest multiplayer software releases on the market is not really an option.
I completed the refund form immediately and have since sent two chaser mails, and have received no responses to any of it.
How long does this take?
