Poor Mr. Baszucki went broken; when my daughter's account get closed after my credit card bank, declined their $9.95 payment, although I called them many times and ask them to re-open her account, they refused.
I'm thinking of filing a law suit against them because my daughter has become very depressed and nervous about loosing a lot of money earned in different games and a lot of friends and groups she has made there in Roblox, she has spent one whole year to built all of them.
Really poor organization and really poor customer support.
I'm so sorry for them.
