Bad coding and bad customer support too!

The problem is that I don't need this bussu anymore and planning to give the account to my mother, so she can learn Japanese. But the way Bussu design the web page is kinda stupid. I used to login with my GG account and never create or change password on the account. Now, I only want to change the password because I can't give my whole email info to my mom. Bussu didn't let me do it. It asked me to give the email address to get a link. The email was never there, even after 20 times I did things to get that god dann email. I contacted the support team and 3 days later (now), nothing from them. Does anyone like me?
