CreditMantri — Taken 1179/- to dissolve dispute, but no action and response post 35 days

I have already paid 1179/- on 29th Jan'21 thru my Citi credit card to dissolve disputes and increase my credit score.

I have already settled my HDFC credit card in 2010. But Still the same is appearing by CreditMantri every time.

I haven't heard anything from CreditMantri's end since 29th Jan'21.
no one answers to emails sent and to contact nos.[protected] and[protected].
Kindly take solid and strong action against CreditMantri right now.
