The worst service provider

So after waiting 4 weeks for a router to be replaced we had wifi for 2 days it went off again. Last Saturday it was reported after waiting the whole week and many phone calls later and a scheduled time vodacom didnt show up. And the esculate the matter to managers and team leaders. What a joke. Now I am told the will only be available the soonest on the 18th of August to repair our wifi. I need internet to earn a living but they don't care about that. Vodacom you need to start giving answers...but they promise a 24-48 hours resolve. Now if they come over a month that should be just great? We have called all lines....tried the inbox on Facebook, even been to a store and this is the service. Its pathetic!
