This messages are related to any subscription..For eg - lets say that you subscribed youtube premium monthly basis by debit card details then during next month bill the amount gets directly debited through your card automatically but if your account doesn't have the sufficient balance to pay for the bill then this message is sent to you from your bank that due to insufficient balance your transaction at POS has declined. So check every app or anything that you may think of where you might have subscribed..just unsubscribe which is not required and all this will stop

I've received a message from SBI of declining pos of rs. 99999999 due to insufficient balance and one more message of blocking my SBI debit card due to suspicious activity while I didn't use my card at any purchase .
