Hi.
Welcome
You should start by ordering a report directly from each CRA.
You can always use a monitoring service but these don't always list everything in quite the detail that the CRAs do.
The quickest way is to just order them online.....but you can also order them by phone or US mail.
As far as monitoring services go, there are several that are good. Here is a link that lists some of them...

Just make sure you get one that lets you have daily pulls so you can check/update your reports every 24 hours and monitor any changes.
