Address: 500011

I manoj jain from secunderabad purchased an i phone 5s from apex parklane, situated at near s d road parklane secunderabad on the date 11/07/2016. Since 2 months getting trouble i went to authorised i phone store and told them about the mobile problems. But the autheries of i phone are telling me it's damaged from your side. As that time repaired by store but fact is that the mother board of the mobile is totally failed. Please look in the matter, because warrenty period will be finished. One more thing as autharities are written it's major dent, but there is not any kind of dent.
