unable to cancel cloud web hosting that I never signed up for

On September 27 I received an email that my cloud services portal had been migrated. I do not subscribe to any Comcast cloud solutions, so this came as quite a surprise to me.

Upon further checking, you added Cloud Web Hosting services to my account on September 27th (and added it to by bill) without my consent! I never subscribed to cloud web hosting.

I have been trying unsuccessfully to get this cancelled and removed from my account since September 28.

Nobody answers at the Cloud Solutions support number, and the mailbox to leave a message was full. The main support number for comcast businessclass says I have to talk to Cloud Solutions and transfers me back to the nubmer with the full mailbox.

I spoke to someone in Cloud Sales who was supposed to put in a cancellation request to his supervisor, but it hasn't happened yet.

The Cancel button in the Cloud Solutions portal doesn't work. It says my cancellation request has been submitted for processing, but doesn't actually cancel anything.

An autoreply from the Cloud Solutions e-mail account says you are are out the office until October 16 and will return my email then.

This is all completely unacceptable. How can I contact someone to get this service removed from my account? I never signed up for it, it was added without my permission, and I'm certainly not going to pay for it.
