Stop Running Batch class called from finish method

Question

I wrote a batch class and called same batch class from finish method without any time interval, Now I am not able to stop it..

global class SaveFileIntoDropbox implements Database.Batchable<sObject>,Database.AllowsCallouts{

  global Database.QueryLocator start(Database.BatchableContext BC) {
        string soql = 'select id from ContentVersion';
        return Database.getQueryLocator(soql);
  }
  global void execute(Database.BatchableContext BC, list<sObject> scope) {
        ....
  }
  global void finish(Database.BatchableContext BC) {
    Database.executeBatch(new SaveFileIntoDropbox(),1);
  }
}

Update I already tried:

string a = [Select a.Name, a.Id From ApexClass a where a.Name like 'save%'].id;
List<AsyncApexJob> lstJobs = [SELECT Id FROM AsyncApexJob WHERE ApexClassID=:a and status != 'completed' ]; 
system.debug(lstJobs.size());
for(AsyncApexJob job : lstJobs) {
   try {
      System.abortJob(job.Id); //01p0k000001ZyIGAAS
   } catch(Exception ex ) {
      System.debug(ex);
   }
}

If System.abortJob is not working for you, make sure you update the Deployment Settings on the org allowing updates to Apex that has pending jobs, edit the batch to remove the chaining and re-deploy (or edit via setup) your batch code. It will then stop once the current instance has finished.
