Domain Setup Issues & Email Issues

Google moved us over to Squarespace. We paid and setup a new page. Everything appeared to be working just fine and in the last week to two weeks everything is throwing errors. 

1. www.fespto.com does not show as a live website now in the browser [this part is working again...for now...]

2. The DNS area of the setup looks off - When they moved us over it was working and now its not. I have tried tutorials  and help and Im frustrated. I can't get Squarespace to help or respond and this is not my area of expertise.

3. Our @fespto.com email will not send to gmail addresses and shows as blocked and I cannot be sure all the email is coming in. This week I have been told emails were sent, but I do not have them and cannot respond to gmail users. 

I think I am just too frustrated to get anywhere. I think I fix something and I may have undone something else. Between Google and Squarespace help...I'm just done. PLEASE HELP

I paid for a domain but it does not show up on my domain dashboard. Where do I find it? I got it through squarespace
