Jammu & Kashmir Bank / J&k Bank — not updating my correct dob

Address:

Lar , Ganderbal, 191131

Applied for cc loan through mpay but rejected since may, 2020 on the ground that department inadvertently while updating information somehow provided wrong dob.
Got new lpc from the deptt along with the correct dob certificate and mailed same through the branch laar (0484) several times since june 11, to cluster head, laps and mis deptts with the request that the mistake made be rectified in accordance with the fresh lpc and dob authenticated by ddo. But have been tossed right, left and centre since then with the same same answer that nothing has been done.
Requested rejected everytime i apply for cc.
