Poor after sales service

I have tried to call in to Supersonic numerous times for my refund but I guess it's fallen on deaf ears. Sent confirmation of banking details and 2 months still nothing. Their whatsapp line has been down since I joined, their Instagram page is down, when I check tickets logged they have been closed with no comments. When you call them, you hold for over 10min. Please can I get a progress report on my ticket logged .Ticket # [SST535630] // ***- Refund request // Auto Responder
