State Bank Of India [SBI] — Harresment

Dear all, this is regarding continuous harresment calls from sbi card team, i have already sumitted a request with sbi to convert my outstanding into emi based options as i had gone through a huge financial crisis and with emi it would be a lesser burden on me. But still am getting calls for a gentleman called ramesh and he claims to be an sbi employee but refuses to share his official email id or other details of sbi. He is constantly after to forward my confidential and kyc documents to a private i'd. Am not at all comfortable to share my documents in to a private email id... Please look into this as i am facing a lot of harassment calls
