Angry and frustrated

I am so unhappy with the service i received from Vuma,i called them a week ago reporting the connection problem,i was told they will send a technicians no one came ,I called again they told me the problem was resolved and the call is closed,I called again they gave me a new reference number, still no one came again they are telling me it has been resolved again which is not true ,still have no connection,didn't go to work for 2 days waiting for their technicians,Vuma doesn't care about their customers,their service is bad, I'm paying them for nothing ,***
