No delivery or any correspondence, 3 weeks later. No email response or call centre assistance.

I purchased a TV stand on 24 November 2017 online, I received no email or sms correspondence from Game, I've emailed and called the customer care centre countless times, and when i do eventually reach someone at the call centre they transfer my call around and eventually tell me they'll call back. I've contacted PayU and they've confirmed receipt of payment and even gave me a reference number, which none of the call centre agents seem to know how to utilise.
