I'd suggest you pull your full credit report and check for ID theft. I'd also suggest you monitor your report and/or lock it down. It's not normal for Comcast to pull your credit six times.
I've asked a Comcast employee to help you. You should expect a reply in this thread.
Hello jewdichop, thanks for reaching out regarding this credit concern! @Nerdburg provided some great information and I can take a further look on my end. Can you please send me a Private Message including the full name as it appears on the account and your full name if different?
I have responded, thank you!
