I had the same thing happen. Stellar Recovery was on my CR as collecting for Comcast. I had a current account with Comcast, never late and no reason for collections. I called and talked to Comcast general line, billing office, and collections dept. who stated no collections. However, they wouldn't provide me anything in writing. I disputed the collection, stating I had verbal agreements from Comcast that I owed them nothing. I listed the name and department of everyone I spoke to. The account was taken off my CR's within a couple days.
