Terrible Product Bad service huge *******

After been a relatively satisfied customer for 6 years,I got a sales call offering me a better deal on my current 2MB line.<br> I was paying R1100/pm this would now be R699 for a 2mb data line.My old line was deinstalled a new antenna and modem given.<br> That was 2 months ago.Since day 1 it hasn't worked.<br> I get 11 Kbps when I should be getting 300 at least kbps.<br> I have spent HOURS on the phone with various Customer consultants.everyone promises to phone me back.NO ONE does.<br> I've asked for this line to deinstalled and my old line returned to no avail.To make matters WORSE my account was debited <br> For R3000 for this installation and now I got another bill for R2500<br> My bill was supposed to decrease.I try talk to management but I get put through to the sales person who sold me the line, <br> He promises to phone me back.Im still waiting,<br> I now have no working internet I have to run my business <br> By hotspotting my I phone.to my expense again and I'm getting <br> Charged R3000/pm when it should be R699.<br> I've tried everything.should this not be rectified immediately <br> I will have no choice but to approach the consumer commission.<br> I have tried to be patient.???
