Cell Fibre does not work properly

I recently “upgraded” from a 10mbps Telkom ADSL line to a Cell C 20mbps up and down fibre line (lines belong to SADV/VUMATEL). So far the experience has been abysmal. Connection is intermittent. There are times when the line goes down completely and times when the speed drops to below 1mbps. I have contacted Cell C numerous times over the last three months, who have in turn logged it to vumatel, my last call to them was well over a month ago. I have also emailed them. The only correspondence I have received was an email requesting me to restart my router. In fact when I lose connection at least 2 times a day I have to restart the router and modem numerous times before I can get a connection, this doesn’t even work most times. If you live in Pietermaritzburg I would avoid getting Cell C fibre, or any fibre provided by vumatel, as they clearly can’t get it to work properly. Furthermore, when Telkom lines go down you aren’t charged for the time that it was down, doesn’t seem the case with Cell C, whether your connection works or not you’ll still have to pay for what you aren’t getting. No idea when this issue will be sorted out, or whether they are able to sort this technical problem out.
