Reliance pco
Not recieved security refund

I am Abdul Gafoor, from vengara, malappuram, kerala, I had given back my reliance pco kit (04943205072). to regional distributer who told me that will recieve DD from reliance within 4 months. I wonder, being a reputed company why reliance is not able to pay my 1000 rupees even after long eighteen months. (Date of refund request: april)
