Income Tax Department — non receipt of tax refund for the year 2017-18

Dear sir,
I am pan card holder no. Aampg5767c. I had submitted my return on 30/5/17 which was processed and a confirmation of the same is on the portal. The return has duly been processed but the refund of rs. 5590/- has not been remitted till date. On checking with the cpc benguluru i am informed that the refund to sbi but they have no information about the same. Could you be kind to help in getting my tax refund please. My bank account details are all updated and confirmed by the income tax department.
Regards,
N. B. S. Gujral
