VDSL Contract but no Service

I have now had my Telkom VDSL line for a couple of months and the line up time lately is horrible. Unfortunately I have a 24 month contract, which I totally regret.. I am now paying a grand a month and not getting even half of what I am paying for. I have a 50Gb cap, of which on average I use about 15Gb seeing that the line is down most of the day, and by most I mean that it is down for 2 to 3 hours then up for 20 minutes maybe. <br> <br> I am pretty sure that I should have a case with the CPA as I am paying for service that I am not receiving. <br> <br> I am so tired of trying to log a call or get any assistance whatsoever from Telkom. They don't respond to online calls logged, they don't reply to e-mails and the call center is joke, I have tried on numerous occasions to call their call center only to hang up after about an hour. (I should actually be reimbursed for my mobile phone charges as I can't call them on the Telkom line because the Telkom line aint working!!)<br> <br> Lets see if they respond to this, although I would not hold my breath!
