Child custody before divorce

Hello everyone, I have few questions regarding marital laws and child custody before filing divorce. I married in 2008. My wife has taken our kid to her home on 28th May (For summer vacation). On 11th and 12th June, I visited my in-laws home to meet my daughter (6.5 years old). Since then there are some regular fights between me and my wife on the telephone. Now she is not talking to me from 17th June and we are getting calls from my brother and sis in law. They are not in a mood to solve the dispute, in fact, they are making things more complicated. We also had the same situation a few years back in 2010, when I filed Restitution of Conjugal Rights under section 9. After that, they have filed 498 A and we had this matter in the woman's cell. The matter was solved and she came back to my home after 6 months. Now the situation is same and I am afraid that they are going to do the same. Also, this time our daughter is involved in all this. I am fed up of all this now and going to file divorce soon. My daughter is studying in 1st class and her school is going to re-open on 27th June. But now, whenever I try to talk to my daughter on the telephone she is disconnecting the phone and no one else there is receiving my phone. I am afraid that they are going to brainwash my kid now. Now, can you please tell me what legal options I have? How can I bring back my daughter legally? Also, if I bring her back without informing anyone there so the law will treat it as kidnapping? Waiting for the advice. Thanks
