No Refund No Feedback

I bought a TV online on Black Friday, but unfortunately it wasn't suitable for what I had intended. I contacted the online support call centre and advised them that I will be returning the TV to the Centurion branch as this was easier for me than to wait for the TV to be collected from my premises. I returned the TV on 3 December 2015 and they advised that it will take a couple of days for the refund to reflect in my credit card.<br> <br> On 10 Dec 2015. I submitted an query via e-mail, but no response received. On 11 Dec 2015, I contacted the call centre and the lady who I spoke to advised she will get back to me. To date no response received.<br> <br> I attempted contacting the call centre again today, but that number just rings. At times it goes through to a receptionist and then she transfers me back to the call centre, but again no response.
