Worst customer experience

So after making a number of calls and sending emails with the required documents to several consultants, my order is still not cancelled and my R3600 is still not refunded. Tammy rep**** here on Hellopeter but still I haven't been assisted. Today I called in again to find out what must I do to get this sorted so I can reorder a TV under my own TV but the call was never returned and no reply to my email. I am looking for recommendations to take action against Game for refusing to cancel my order and refunding my money. This is the worst customer service ever and needs to be addressed. It has been two weeks already and no one has been helpful. I don't think this is a trustworthy business to deal with and it's disappointing for such a big company.
