False Cases of 498a against me and my family.

Dear Sir, I have been victim of false 498A case against me and my parents, I was married in 2014 and soon after marriage wife cheated me and went to his native place and filed several cases, of 498a DV, Maintenence I have won the DV case as she failed to produce proofs and the court disposed the case and order is in my favour. I have filed Null-n-Void case which also i won on the grounds of fraud marriage. Now after 4 years the 498a case is going on and several times myself and my sister and parents has to go to court and every time police comes to sisters house to arrest before the court date. Any advice will be helpful, what should i need to do in this stage, My laywer most of the time does not appear in the court and not giving me any doccuments even if i think to change the laywer. My case is in Vadodara and my x wife stays in Gandhidham, she never appeared in the court. Please advice if Null - n Void and DV orders can be helpful in 498a cases. Thanks Jeetendra
