"A Record www" missing on Homestead.com end.

wiltonmanorshandymanservice.com is one of my sites that is missing the www in the A record DNS on Homesteads end. There are other sites in my account that are also missing the www A record on Homesteads end. As of now Homesteads system will not allow me into the Advanced DNA settings. Do I need to call technical support?

@elyzabethv​ Now I'm stressed, the website and all its links were working fine without the www. 

Based on your comment, I had technical support add the "A Record www" in the DNA settings, and now all my website links that were indexed on the internet are not working. Do you know if this is a temporary thing that I have to ride out for 48hours? Or are those links now permanently dead because of the change by Homestead? I am feeling like I made a mistake by having them make the change. What is your opinion?

@elyzabethv​ It has been two days now since tech support added the www to the "A Record", and the site is still not up and running. Does tech support know what they are doing? The second tech that I spoke with said that the first tech did it wrong. So now the blame game.

How do I get this site up and running? This is stressful. There was absolutely nothing wrong with the site or indexing until I had Homestead.com tech add the www to the A Record.

How can I contact? I need a manager or a tech that is not going to sabotage my web presence.
