Nvsp — not responding to my request

Address: Sonipat, Haryana, 131027

I am Vishal of village Asadpur, Sonipat, Haryana. I applied for voter card 1 year ago in my village through Aanganwadi. I submitted all the required documents. When the form for correction came I saw there was mistake in my father's name.
My father's name is RAJESH as in my all documents. I made the correction in that form. When the voter card came my father's name was not corrected. Rakesh Kumar was written in front of my father's name. Then I applied for correction on online portal nvsp.in . 3 months have passed from the date I have applied but there is no improvement in my correction status. My reference id is OKX[protected]
