Interest on Credit Card at higher rate not permitted even by National Consumer Disputes Redressal Commission(NCDRC)

HDFC Bank had charged me interest at a much higher rate inspite of Case decision of NCDRC vide case CC512007. I had been following up with HDFC Bank to recalculate the interest and share the actual amount outstanding but all in vain. Now ,they have blocked my savings account have balance of Rs.11000+ by way of lien under the clause of their terms and conditions and that too without intimation to me.
They are not accepting nor denying if the case law of NCDRC is applicable to them.

What do I do???? Please help…..
