State Bank Of India [SBI] — Fraudulent activity from SBI CREDIT Card Department

Recently I have been receiving messages from SBI Bank stating that my application for SBI CREDIT Card has been rejected at first I thought it was a spam or is sent by mistake from their end, but recently I am receiving these messages quite often like Every 2-3 days and that too from their particular specific domain whereas i haven't applied for anything as such. I really don't expect such fraud from the bank of Our State Atleast. It's really not acceptable. They are misusing our data just to complete their target without our consent. Are they even aware how it's going to affect My CIBIL?
