Sitestar (Velocitus) Sitestar OneWest Continued sending a billing after I cancelled their service. Lynchburg, Virginia

I signed-up with a broadband internet service and emailed Sitestar to inform them that I no longer wanted their dial-up internet service.
They kept harassing me with bills after I discontinued their service.
They claimed I had a contract that required that I write them a letter that I was canceling their dial-up service.
Meanwhile, they kept billing me!
I finally had to write and mail the letter.
However, I had to pay them $29.90 to close my account and get them to stop further billings.
