Canara Bank — I'm complaining about bank account.

Address: Narayana Hrudrayalaya Branch. Bommasandra, Branch.

My Canara Bank account has been working for about a year now. When trying to send money, it'll say it's having a mobile number mismatch. For so long I've been trying to solve this problem but the branch can't even find out what's wrong.
Today, I decided to try through the internet Banking and it states I have a high severity memo placed in my account and after finding out what it means, I found out they placed this on my account without any information to me or whatsoever.
