Service and online challenges

Recently bought a drone online which was faulty within 14 days. Was told to go in store and then told to log the request online for a replacement. Then told they have no stock. Sending approximately 20 emails back and forth and still no refund in my account. It’s like a dead zone dealing online as there is no contact apart from email. The store in Pavillion trying to hell but they don’t return calls either. Absolutely Pathetic service. Be warned if you order online.
