Supersonic ********** activity

This has been the biggest regret and nightmare of my entire life. If only I had followed the suggestions on my broadband.co.za Started with courier not delivering my simcard. Then went and collected some but it could never connect. The poor inexperienced call centre tech person eventually the humb sucked that my B618s router, that works with every other simcard and service provider, including rain, is incompatible with MTN Supersonic. Eventually after numerous un-returned calls, whatsapps and emails I insisted that my not working contract be cancelled. To my utmost surprise and disgust. I have been billed R1731.17 for a service that has never worked from day one and over and above all the above issues I was billed for a different sim card number than the one I received. I am still not getting any replies or calls from them and will consider seeing the ombudsman because this is *****.
