Address:

Visakhapatnam, Andhra Pradesh

I was a customer of city bank and i took homelone from this bank. i was insured for my loan account at birla sunlife insurance company.
now i have cancelled my home loan at citi bank and i have transferred it to state bank of india.
when i asked about my insurance amount at citi bank, they asked me to enquire about it at birla sunlife insurance and when i did the same, these people at birla sunlife insurance company didnt give any proper information.
again i visited citi bank for the same, and again they asked me to write a letter regarding cancellation of my insurance amount and said that i'll be replied within a month after i post the letter through courier.
i wrote a letter stating to cancel my insurance account and return the remaining amount to me at the earliest
and couriered the letter to their main branch at chennai.
i didn't get any reply from them till now though it happened three months after i have posted the letter to them.
please assist me at the earliest.
