Dear Ashish,
This is a classic case of hardship faced by assessee due introduction of section 206AA. Before I can suggest any possible solution, please let me know
1. Assessment Year
2. Date of filing return
3. Date of assessment completed and refund given.
4. Whether assessment was processed without caling you u/s 143(1)(a) or whether they had called you for the scrutiny.
5. Whether PAN existed but not given to bank or whether you took PAN after the deduction?
6. Whether bank had asked for your PAN? Whether you had provided them at the time of filing up form of FD etc?
