Makro doesn't wanna refund me for an item that wasn't delivered

I bought a titanium entertainment unit on the 17th of November and Makro failed to deliver, I then asked for the order to be cancelled on the 22nd of November and I was promised that the order will be cancelled. I have been calling, sending emails, writing on hello Peter but it seems like Makro is not interested in giving me back my refund. Whenever I call, they tell me that they will do a follow and place the matter under urgent ones, i write here on hello Peter and they promise to contact me in 24-48 hours of which they never bother to, i send emails and they just ignore them. All i want is my money back, it has been more than a month. I just don't understand how difficult it is to process money into my account. Your customer service at makro is something else, you just have to have customers following you around to get what's theirs, this is not on at all. Can I please get my money back, this is now draining, time consuming and I've been wasting my airtime and data and I'm not going to be compensated for that.
