WORST domain provider aka Squarespace

I was super happy with the domain management provided by Google and all of a sudden I am forced to use Squarespace. Initially not having an issue with that, turns out I do in the process. NO clear email structure, I cannot purchase bulks of email IDs but have to do it one - by - one ... I Cant find a domain I bought through squarespace. Is there a way to get away from it and back to Google or is that it?
