I used to be a customer of Comcast, but left them a long time ago for another ISP. When I started doing business with Comcast, they performed a credit check on me. At that time, I had no issue with it - I figured it was fine, as they wanted to make sure a new customer had the capacity to pay for their service(s). When I terminated my contract with them months later, they performed another check against me. I couldn't understand why a company would perform a check on someone no longer doing business with them, and was somewhat concerned.
When I went in-store and inquired about it personally, the clerk told me they could confirm the first credit check (again, something done with new customers), but the second was unknown to them. (I have a record of their inquiry on my credit report around the time of termination of my contract.)
It has been well over a year since I ended my contract with Comcast, and it never really struck me to ask until now:
Is this normal for a(ny) company to perform a credit check when business is no longer being done between the two parties?
My concern is that the latter check could have had a harmful impact on my report.
