Vodacom is ****ming me!!!

Vodacom is ****ming people with their home internet data deal. I have been struggling with the network since the 2nd of Jan.. when i reach out to them they say they're aware of the issue their technicians are busy fixing it. It has been 5 full days since they've been saying that. I message them everyday and yet they sing the same song "Our technicians are busy try to resolve the issue". When i suggested to pay on a pro rata base they shot me down fast.. told me I was going to be in arrears. Why should i pay for services that aren't being rendered?. Unfortunately i cannot attach images here but i have all the proof of my communication with their teams.
