State Bank Of India [SBI] — lost 1500 in state bank buddy

Seriously this is one of the pathetic app, i have seen till date. Lost my 1500 rupees as my registered number got discontinued. They don't have a process to send the otp in email address which they took during registration neither they can refund the money to my bank even after providing all details to the customer care. Its been more than year but still didn't receive resolution from their side. Would recommend against it to all the fellow customers. They would rip you off.
