Poor poor service

Hi I have a 24 month contract with Telkom for a internet service including line rental and a four meg uncapped adsl service. At r800.00 <br> Firstly it only works once or twice a week <br> <br> Secondly when it works i only have a 0.5 meg download speed<br> You hold on for hours when contacting the call center <br> When using the online reporting structure they contact you in 2 weeks from reporting a fault <br> I am tiered of paying for something I'm not getting
