Consumer Redressal

A PHONE CALL CAME FROM 926667140 OFFERING MANY SERVICES AGAINST MY SBI CREDIT CARD. THOUGH I WAS NOT NOT INTERESTED IN RECEIVING THOSE SERVICES THEY WERE JUST INSISTING ME. THEY WERE ASKING FOR SEVERAL TIMES WHETHER EVERYTHING WAS CLEAR TO ME. AS SOON AS I SAID YES ON THEIR QUESTION OF BILLING THEY ARE PRESSURING ME TO CONNECT TO MY BANK TO PAY THEM. I ASKED THEM AT ONCE TO CANCEL THE DEAL AND THEY ARE CREATING NUISANCE AND INSISTING THAT THEY CAN'T CANCEL IT AND THREATENING ME. I REQUIRE YOUR SUPPORT AND I DON'T WANT TO GET CHEATED.
