Pro Sites messing up client site

1) My customer signed-up for a site under https://produtocervejeiro.com
2) Their site is https://produtocervejeiro.com/growlerbags/
3) Suddenly, my user (growlerbags) can't access their site. Pro Sites says it was never a Pro Site, but this customer did the proper procces, and paid.
4) It was working until I've made a Domain Mapping to https://growlerbags.com.br/
5) Now my customer can't access their site, they're redirected to Pro Sites Page, but they've already did that, and they need to work. I'll be offline for a week starting from Tuesday...

Please help me! I need to get this back working ASAP! Tried Live Chat (says 6 minutes but I was waiting for about an hour), and this customer is very important to me.

Thank you for help, tomorrow when I wake up I'll try again the Live Chat.
