Consumer Redressal

Myself Pallabendu Halder pursuing Ph.D from Bidhan Chandra krishi Viswa Vidyalaya residing at Kalyani. My home town is Canning Town, South 24 Parganas. I bought a leads water purifier on April, 2013 with one year warranty in my mother name (Gayatri Halder). After completion of one year we have made a AMC (annual maintenance cost) for that above water purifier through "JAYASHREE SERVICE CENTER", Narendrapur, South 24 Parganas for one year 22/06/14 to 21/06/15 with spending a amount of Rs 5200/-. But for last 2 to 3 months it was in non functioning condition, and we called the centre for several times but they didn't replied and still now it is non functioning. Please help us out from that problem as early as possible. The voucher of AMC copy has been attached for reference, please go through it.
