Dear sir,
VI have purchased your battery 42B20L ( sl.no - AAB0248P203837)on 29/03/2016 vide bill no 309, TIN - [protected].
Going through the matter briefly that my battery is discharging in 3 days in regular basis after 18 days of purchase. But after several cocomplain lodged at your service center jeypore, dist : Koraput, Odisha, he is just ignoring to exchange my battery. I have already haned over my battery 4 times in 3 month but the result is same. It's a kind of mental harassment on my part. So plz look in the matter do the necessary steps in favour of me.
