Lava Mobiles — Serviced my lava x81 without my knowledge

Address:

600083

I am given my mobile service regarding hanging and not charging. If there anyother major problem should say to me and do the service so that we have also said that without my knowlege should not service. But without telling us he serviced my mobile and said ringer wont work in the phone. What problem we said that is not solved, instead os that he made another problem.
