No refund and customer service

I placed an online order for a device. The expected delivery date was 10-14 working days. I received no feedback and when I contacted the online support, I was informed that there would be a delay and the device will arrive in December (almost 3 months later). I asked them to cancel the order and to provide a refund.

After multiple emails and correspondence, including a request for my bank account details, I have received no further update or response from the company. When I call them, it goes to a voicemail to send an email. The refund has still not been paid.

I am still awaiting feedback and a refund (close on 7 weeks now).
