Asus Charger - warranty replacement

I purchased an Asus laptop for R18K in early June this year, which comes with a 2 year warranty. The charger is faulty. Asus referred me to Ensure Services for the warranty replacement. For two weeks I have been emailing and calling Ensure Services for assistance. To date I have heard nothing. Not a return call, 1 email, to confirm receipt of my email. My son uses this laptop for University CAD Architectural studies with upcoming assessments and projects. Without the adapter charger, the laptop cannot be charged and used. Why should I go out and buy another Asus charger after having spent R18K already on the laptop which is only just over 2 months old. You just don't answer emails. Apparently there is isn't a manager or supervisor that one can speak to, you can only email them. Emails return a read receipt from India. I ask with tears in my eyes, how they can assist me. They aren't even on the same continent. I have never experienced such a poor disgusting service in my life. They are giving Asus, Dell and all the other PC suppliers that they represent a stinking name. Shut your doors Ensure Services, you are a waste of time and money.
