If you want a FICO score, Score Watch is the way to go. In case you didn't know, equifax.com doesn't offer a FICO score, it's FAKO.

Just because you pay a bill doesn't mean it gets reported immediately and thus, you won't see the change in your score immediately either. Updates after a payment is made are initiated by your creditor - probably monthly - just after your bill is cut. You might be able to find out that date just by calling customer service or by keeping track on a CMS. 

So, perhaps you need to reconsider when you check your score/reports. That way, you won't be so disappointed. 

Good luck and congrats on paying off 2 cards. I'm sure you'll be please with the score bump when they report to the CRAs.
