Telkom Internet line DOWN for 3 days

I logged a call for slow speeds , paying a premium amount for a 20MB line and only getting 5 MB for a long while now , a day later my line gets disconnected and now 3 days later im sitting without internet after contacting telkom multiple times.I rely on my internet as i work from home this has now affected my budget and still i must pay them for a line thats not working and my 3G cost . this is pathetic honestly how can you call yourself a service provider when you offer a service you cant deliver , i keep getting told no the call is with a technician and has been escalated but nothing has been done except cutting off my line is it due to technicians lack of professionalism or the company cant produce the service they offer at a premium rate .
