They are very bad at customer service. I mailed them to cancel the order from their website form instead they shipped the order after 4 days of mail and not replied anything on mail.
Later they said order is shipped it cannot be cancelled and refuse to accept the shipment to get refund it has been again more 4 days I returned the shipment yet no communication. I guess I need to file a case or request for chargeback through my credit card company.
