PLANET SPARK - Refund required for deposit money

ATTENDED A SESSION FOR MY Daughter FROM PLANET SPARK TEAM. THEY ASKED ME TO PAY WHOLE AMOUNT OF RS ** K NEARLY THROUGH CREDIT CARD INCLUDING RS *.*K AS Initial AMOUNT. I URGE THEM TO GIVE TIME BUT THEY DENIED. IN PRESSURE I PAID RS **** AS INITIAL AMOUNT. BUT LATER ON NEXT DAY I REALISE THAT CLASSES THEY ARE OFFERING IS LESS. I REQUESTED PLANET SPARK TEAM TO DEPOSIT EMI MONTHLY. BUT THEY DENIED AND I DONT WANT GIVE WHOLE AMOUNT Without TAKING ONE MONTH CLASSES ATLEAST. I REQUESTED THEM TO REFUND MY INITIAL MONEY BUT THEY DENIED.
I WANT REFUND OF MY INITIAL AMOUNT AS I HAD NOT ENROLLED WITH THEM AND NOR TOOK ANY CLASSES.
