Poor service

I ordered wifi from webafrica, they called me to schedule an installation. On the day of installation they did not honour their appointment, I contacted them and they rescheduled but still no one came. This went on for 3 weeks, I got fed up and I asked for my refund of R399 and they said it'll take 10 to 15 days. It has been a month and I haven't received my refund, every time I contact them they tell me they escalating my query, worse they don't have a direct line where I can call them, I only communicate with them on watsapp which the communication is not effective as compared to a phone call. Their service is the worst, never seen anything like this ever, I feel ****med right now by webafrica
