Is this support have free of charge?

There is no charge to diagnose the problems so that we can determine the steps required to fix the problems. If the steps required to fix the problems will be found to be complex, then we do have to charge to fix the problems completely. The fee depends on the complexity of the steps involved, and I will let you know the charges applicable; later you can decide whether to continue with the complete fix or not.
