Tata Capital — After taking all my details personal loan not disbursed

I got a call from tata capital for pre approved personal loan they took all my details even carried the auto debit formalities from my bank account details
They are highly irresponsible and unethical as they don't reply nor they pick the call
Call keeps rotating from one account to another
And now one of the employee says as the system has been updated you loan is not approved
Highly unethical behaviour from tata capital
Dint expect this from the company
