It is true that their support ticket is very slow and they took almost two weeks to reply my ticket about registering a new domain. But I never had to wait more than 3 minutes to get live chat support. My ticket was solved instantly via live chat.
Another good thing about ASO is their server name and user area interface is very unique and user friendly.
Hope ASO will remain consistent with their good service. Best wishes for ASO team! Thu gọn
