Clicks Refuse to send me my product!

On Friday 24 November I bought a Polar A360 from clicks online. My order failed but my money went off my account. I have been battling with clicks call centre for 10 days now. I have sent them proof of payment but they refuse to send me my product. I have spent over R150 phoning them because no one seems to bother phoning me back. This is unacceptable!
