DEAR SIR,
I HAVE PURCHASED A TOSHIBA LED TV(32″).FROM “GREAT EASTERN TRADING CO.’AT TOBIN ROAD AND THE TOTAL COST OF TV WAS RS.17000 FROM WHICH I PAID AS DOWNPAYMENT AMOUNT RS.5670 & THE REMAINING AMOUNT WAS RS.11330. THIS AMOUNT(RS11340)I PAY TO “BAJAJ FINSERV LENDING” AS EMI RS.945/MONTH UPTO 1YEAR. IT WAS STARTED FROM 05.02.2013 AND WILL END 05.01.2014 . I HAVE ALREADY PAID 3 MONTHS EMI WHICH IS DEBITED FROM MY SBI A/C..WHEN I CHECKED MY A/C DETAILS I FOUND THAT MY SBI A/C DEBITED RS.1,008 I WAS SHOCKED BECAUSE MY EMI AMOUNT IS RS.945 WHERE I PAID RS.63 EXTRA AMOUNT.WHEN I ASKED ABOUT MY LOAN FROM BAJAJ FINNERV CUSTOMER CARE THEY TOLD ME THAT EXTRA AMOUNT IS ADDED AS EXTENTED WARRANTY AT TOSHIBA LED TV.
NOW THE PROBLEM IS THAT COMPANY WITHOUT INFORMED ME HOW CAN THEY ADDED SOME EXTRA AMOUNT IN MY LOAN AMOUNT{(945+63)1,008}…
WHEN I BOUGHT TOSHIBA LED TV. WITH 3YRS WARRANTY THEN WHY ADDED SOME EXTRA EXTENDED WARRANTY WITHOUT INFORMED ME.
I DID NOT GET SOLUTIONS …SIR KINDLY REQUEST YOU TO PLEASE SOLVE MY PROBLEM..
