Worst service ever and worst policies. Not at all satisfied with both service and purification levels. I have to run behind support team every week and call 100 tiles until they show up and still won’t resolve the issues even a single time. No support team availability no standards and they won’t even refund you if you ask for cancellation. BE AWARE OF THIS FRAUDULENT SERVICE. I really don’t understand how people are still trusting this. They won’t refund you at all. And won’t even provide proper service.
