Hii,
I had transferred 25500 from rbl credit card to my bank account through which i had setup an emi for 12months through which my em i amount every month should be of 2300/- i received a text today that i have to pay around 12000 by 12 dec 2017 through which i have already done a payment of 15500 to the rbl credit card so my balance should be almost 10, 000 to pay my credit card so can any one tell me what is going on... Why i am getting such a big amount of bill to pay this month to clear my dought i try calling help line no.. But the ivr dose not accept my dob through which i cannot get connected to the customer care excuative and clear my dought for the things that i am looking for... Please look into my matter
