The worst sevice i've ever expirience

At the end of October I app**** for an ADSL line with router for R799, on the 2nd of November I received a welcome sms with my username and password. I was then asked to pay R700 deposit which I did then when all was approved they were getting ready to install. I put the installation o hold for a week as I had some issues at my complex after then I gave the go ahead to install. After calling the customer care every second day and going to different Telkom stores where I didn't get any solutions, my router was only installed on the 20/12/2017. This is by far the most pathetic service I have ever come across and it doesn't end there, upon installation the Technician calls me, as I was not home but had arrange for someone to be there, and advises that I will have to call the customer care centre to downgrade my line speed for my internet to work. I called the Telkom customer care centre on 10210/10213 and a consultant advised me to fill in a document and email it to them and I did. After again doing endless follow ups with them eventually another consultant logs a call over the phone and advises me that it will take another 48hrs to 21 days to resolve this problem, till today I haven't been able to access internet at home. now hows that for service that you are paying for?
