CYBERSMART - SADV - SLOW CONNECTION - POOR SERVICE

I signed up for a Fibre Home Internet Account with 50MB down and up speed. The installation was done very promptly however when following up on when the router was to be sent, we kept being told Monday, this happened 3 times. Finally we receive and install the router only to find that the connection was incredibly slow. On average between 5MB and 15MB Down and UP. When querying with Cybersmart they just inform us to use LAN cables which even when we do the speeds do not change. After numerous calls, emails, speed tests after speed test, finally a week later the issue is escalated to SADV. I now receive a bill for over R1300 for a service I haven't even started using yet. I currently still have a Fibre line with Telkom at 40MB Down and UP and to be honest was trying to move away from Telkom but this whole experience makes Telkom look like the much better provider. The whole experience has left a bad taste in my mouth and will not be recomending Cybersmart to anybody due to the way the situation is being handled. Nobody calls back, no emails are returned and I'm still left with a slow connection. I've requested to cancel the account but interested to see how they expect me to pay for a service I haven't even used. Perhaps I've just been unlucky, nevertheless, I feel people should know so that they may make a more informed decision as to which is the better ISP.
