SBI Blocked My NRI Account and Demands Costly Attested Hard Copies for KYC

SBI blocked my account alleging inadequate KYC verification, and the situation has been quite irritating. They said they wanted printed copies with attestation, so I quickly emailed them the necessary paperwork as directed but they rejected it. Getting documentation verified where I live costs £60 each document, and as an NRI they are requesting several documents. Not only is this method costly but also somewhat time-consuming. When I told their support personnel about my circumstances, they were useless and insisted on using strict policies without providing any options. My account has frozen, hence I cannot get my money for pressing necessities. SBI has to rethink its NRIs' policy and provide more workable answers.
