CreditMantri — availed service for credit rating improvement

I paid 1900 plus taxes, 2300 for helping to settle my disputed credit card. They could manage to get the details of the same. However i went to the bank and settled the amount.
Credit mantri website didn't update my payment. Their customer care gave no response at all. When i emailed them, the response to it seemed completely different than my query.
Extremely unhappy with the service. They claim they can get good rate from banks which is completely misleading. I want my money back
