Hello, sorry to hear you’ve not received an answer - but the support site is the only way. Perhaps try making a new ticket and providing as much information as possible initially. I also don’t recommend emailing every day. That is not professional and you must recognize and respect time it takes and others email also, so spamming will not help you.
Wishing your friend the best and that he’s able to recover his account, but the forums are not the place to post about it. It is handled entirely with the support.toonslab.com site - thank you for your patience.
