Telkom terrible service

I'm very dissatisfied with the service I've received from Telkom. We are a business which is reliant on internet because we use it for online training, downloading service manuals, flash file etc on a daily basis. Our internet service has been down for 2 weeks and cannot get a proper answer from Telkom as to why? We have been logging complaints but nothing has been done. Asked the supervisor from the call centre to contact me but nothing as yet. They told me to go into to a Telkom to get a data sim, I waited 45 minutes for them to give me a sim then tell me to activate it on the telkom website, Really? I don't have internet, how am I suppose to activate it. We are losing business on daily basis because of this terrible service
