WebAfrica messes up line switch over and billing

Two issues I had during July/August: 1) Switching over a line when moving house. I did this through their Client Portal, as instituted by an agent. When I received the email that the line was active and I just needed to plug my router in, I did so only to have no internet connection. After a week of phone calls lasting hours, Vumatel coming three times to check, it was eventually sorted. (In this process I was hung up on multiple times and received useless service via their WhatsApp line). 2) I noticed my billing amount was unusual (three payments taken from my account instead of one). I contacted billing to be informed that they had put the new line in my old flat as well as the new flat and they somehow billed the old flat twice. They said they would rectify this. I asked when I would receive a refund and she put my on hold (on a WhatsApp line?!). She then ended the chat without confirmation. I am still awaiting a refund for over R1000.
