Punjab National Bank [PNB] — laps in interest against scss

I am senior citizen saving account holder in pnb kakrola mor new delhi. My a/c was transferred from army post office in dec 2017. I was paid interest up to oct2017 by post office and there after by pnb. However interest of one quarter (Oct to dec 17) is not paid to me. The bank statement reflects that the same has been paid but not credited to my a/c.
The bank manager is not co-operating at all despite my request to go through the matter but all in vain. He is compelling me to lodge a registered complaint. I have recorded his furious arguments in my mobile. My details are as.
