NO service from Vodacom regarding faulty tower in the area

Going on to the 3rd week with no signal, unable to use my phone at home. Paying for data and a phone I’m unable to use after the tower in the estate has given issues. After promising that they are sending people out to look at the tower, still nothing 2 weeks later. Have been to the Vodacom store in the area and they are also not getting any feedback regarding this matter anymore. What else needs to be done? Can't carry on like this
