Placed a charge off on my credit profile that was a fraudulently opened account with Comcast that Comcast stated two years ago was a mistake. Would not send me proof of the charge. Forced me to spend 4 hours at my county sheriff's office filing a fraud report for an account previously reported and accepted by Comcast as fraud. Clearly these people buy garbage accounts for pennies on the dollar and seek to extort people who are too buys to spend 4 hours to prove innocence. Terrible practice. Should be sanctioned.
