Quick to take your money, slow to refund you

I ordered an Android tv box from their online store in May 2020 only to find it never had Netflix installed and was not compatible to download Netflix. On 22 May 2020 I requested a refund to which they said I should return the device to my nearest store. On 23 May 2020 I took it to the West Coast mall store in Vredenburg and was told that they do not have stock of the other Android tv device. I told the guy to do the refund so long & call me once they had stock, but he told me he could not take the device from me, I have to wait and check when they have stock of the other device before I can return this one. I checked for the whole week and they never had stock so I requested a refund and I was told that I need to do the refund with the online shop. I managed to get hold of the online shop on 28 March 2020 and they told me I must do the refund at the store. On 29 March 2020 I went back to the store and requested the refund there again and they took the device from me this time. They let me fill in a form and told me the refund will be processed in 7-14 working days. After 14 working days I still did not receive the refund. I recieved an invoice for the refund from the online store, but no refund. I managed to get hold of the online store again & they told me someone would call me the next day regarding the refund. A week later still no callEd from incredible connection so I called them once again. They gave me another reference number and told me if someone does not call by the next day, I should call them again & have the matter escalated to management. Still nobody called me the next day & I then escalated the matter to management. It’s been a week now and I was still not contacted by incredible connection or their management. Altogether its been almost a month now & I still do not have my refund.
