I have purchased ?original Nokia battery from New Gujarat Marketing,R-5&6,1st floor,jagadish market,abids,Hyderabad.Ph-040-******** shop owners cell-********59 on 25/02/2011.When i purchased the battery the shop owner just made a small plain paper receipt of Rs.480/-. After using the battery for 2days i had a problem of easy discharge of battery. It works for only 2hrs. when i approached the shop owner he just told me to contact Nokia customer care.I approached the Nokia customer care they told me to get original bill from shop owner. when i again approached the shop owner he refused to give me the bill,started arguing and threatened to beat me. As i could not do anything i calmly came out. My request to consumer complaint board is to take strict action against such shop owners who are making fraud by selling duplicate batteries into the market. It is very difficult to identify which one is original and which one is duplicate. They are making huge money without paying taxes to government by issuing plain paper bills to the customers. Such shop owners when we approach first time they speak sweetly and when we go again with a complaint they not even listen to our complaints. I request you to take strict action against such shop owners.
