Idealdirect are inefficient with refunds

In Jan 2018 I ordered an S2 Magnet Sport Bluetooth headset for R299.99. Instead I was supp**** with an S3 Sport Clip on Bluetooth headset. I specifically wanted the hands free option. I made contact with their exchange department on 17 Jan. They wanted me to pay for the courier fees to return it to them although it was their mistake. I hand delivered the S2 on 27 February to their offices in Crown Mines. I have been advised that a refund was processed to my account on 15 March but this has not happened as yet. In the interim they have changed their contact details and the new number just rings. These companies are very quick to take your money, deliver what they want and then let you beg for your refunds. It is unacceptable that this has now taken over 6 months and many emails and attempts to reach them telephonically. I will not recommend that anybody buy from them again. Their aftersales services does not exist.
