IDBI Bank — FD matured on 1-4-21 but proceeds not credited till now.

Online FDs do not require surrender if the documents and are repaid automatically on maturity dates bit IDBI delays in such payments.Lors of follow up already done but still process not credited.Dies the bank pay additional interest any time for the number of days the maturity proceeds are credited late?Surprising that such policies are followed by banks against public interest.Tge private bank is minting income for itself by earning interest on our money.I think the government including RBI should take action against such banks unfair policies.
