You have to request the banker to file a correction statement with NSDL giving correct PAN No.
That is right.
That is not correct. If pan data such as name and no is a mismatch, they will direct the bank to pay TDS @ 20%.
That is not correct your income has been reported to income tax department by the banker later on department will collect income tax with penal interest.
This is a short sighted policy and you cannot run away from the income tax department.
