Almost 60 days has passed and not came a single notification or message about mony by canara bank.
I contacted canara bank costumer care and ask them about refund then they said to me "you go to your home branch and ask them about it"after that i visited home branch and i met branch manager they rudely talk to me and said i don't know about it, after that i have written a complaint and gave them.
