Business Line Faulty and Ignored

Our business line went down on the 16th January and came back on the same day so I was very happy with that side. Then, on the 19th the line went completely dead. I reported this immediately and was asked if we have a switchboard and that if its the switchboard we will be charged a call out of R1,399 WOW but to be expected. I subsequently had the switchboard looked at and was told it was definitely Telkom line but now Telkom are nowhere to be found and its now the 23rd Jan. Can't get through on the phone, it just rings and rings. I downloaded the App, oh my goodness what a joke that is, it wouldn't open, or work and when I eventually got it going it told me I am not the valid person they need, I'm seeing red by this time. I report it on FB and get a wishy washy reply to say they have escalated it. When I send another message saying I'm reporting this to Hello Peter as that's the only way they respond I get told my reference number is now in the process of being assigned to a technician and he will contact me when he is about to attend to it. Business line, costing us goodness knows how much lost revenue and its taken from the 19th to the 23rd to assign the number. Get a grip Telkom, you are sadly lacking in service.
