Paisabazaar.com — complaint against free cibil report

I had checked my cibil score previous month after i login in paisabazaar. They claim for providing free cibil report. But actually my cibil score got reduced after getting through the process. Even i am frequently getting calls from them regarding cibil reports. Now i am afraid if my score gets further reduced due to their calls frequently.
I feel that people should not check their cibil score on their website even though they claim it as free report. Be aware!
