But till date no positive reply has been given to me from both of the PO though I contacted with Suratgarh SO by telephone many times.
My said KVP has been maturod on 7/7/19 but I am failiure tpo receive those money till date, you can imagine Suratgarh is so so far from my home destination and I can't appear there physically.
