I recently was signing up for service at a new residence and he said that there was a $25 fee or a credit check. When I asked about the credit check, he said it was a quick look and the same thing that my other utilities companies had done. Instead it went on as a hard inquiry.
Additionally, I've been a Comcast customer for 15 years and should not have had to go through this step. The accounts are not linked, despite having the same SSN and phone number attached to both accounts. It appears that the agent set up a second account instead of linking the two and then did a hard pull instead of soft. It looks like Comcast only does hard ones, but that was not what I was told.
