Hi there and welcome!
I must apologize, I have done things in reverse order and had someone setup the new automated billing system ahead of this site being updated.
If you are wondering where that email came from, my name is Brent Guild and at some point my wife and I have helped you with a website that is hosted on our servers.
I have just installed an automated billing system for recurring costs such as hosting and domain registration.
If you clicked the wrong link and arrived here looking to pay your bill, the billing system is: www.circlevision.net/whmcs
Thank you for your patience and your business 🙂
