Game Refund , Zero Accountability, Poor after sales service

From the 5th of November, I have been waiting for Game Pavilion to refund me for a fridge that I purchased online. Since then its been multiple calls from me but zero feedback from support and no replies on emails either. Every call has the same responce, " I will get the agent to call you back or I will call you back". I have spoken to the Line Manager Adam from the online support, and Adam promised me email confirmation by 10th of December and that my refund would be processed, but I have not had any email since that call, they have no SLA's, and there is no accountability, and when requesting a time line for a return call the call centre agent Ivonia said that she can not tell me that, as it would depend on when the agent sees it and that could be even a week or next year. The Line Manager on Saturday also promised me a call back, and still no call back. 2 tickets were also raised on WhatsApp, with zero response. Game/ Massmart Support throws around words like escalation, but it's not tied to any deliverables, and zero communication. Worse still is the store that cannot answer and basically gives you the same promises with feedback and call backs, but you can never speak to the person in charge; you're just pushed around blindly. It's now more than a month, and still no refund and zero communication. 27 calls from me with no resolution. If you have a choice, think twice before supporting these guys. This is my second issue with them as a group(Massmart) and the after-sales service was the same; a one-star rating is too much.
