After sales service at Vodabux store appalling

We bought a Mellerware toaster and kettle online from the vodabux store. We paid cash. When the goods arrived, there was a defect on the kettle. We called vodacom and logged a complaint. Months later we still did not hear from them. Again we called the the 082135, we spent what seemed like an eternity on the phone, we were passed from one department to the next. Finally we spoke to a Marianne from the Vodabux Loyalty department. She took all our details and said she was going to speak to her supervisor and get back to us. She refused to give us a reference number. Two weeks later, still no response. We emailed the customer service department, they messaged us to call 082129 and select option 2. We did that. The automatic response is about porting our number. Really what does the purchase of appliances got to do with porting a number. Right now , we are at our wits end and we just want the appliances, still in its packaging and box , collected and our money refunded. I would never recommend anyone purchasing from the Loyalty vodabux stores. The after sales service at vodacom is appalling.
