Further i have talked to cenara bank customer care, they have guided to complaint to concerning bank. So same day 03.10.2017 i have done a complaint to sbi customer care and got a revert message that your complaint has been registered and will be resolved within seven working day which ticket no was [protected]. But after passing more than 12 working day problem has not been resolved and also got disappointing reply from customer care that i will take some more time, further i have visited my concerning branch sbi anpara several times but i have got disappointing answer as well not lodged any complaint in my knowledge. Now i became fed up, so i am requesting via this message that if some authority will take initiative then this problem will be resolved and i will be thankful.
