Worst service

Worst service ever. I had an installation in November however the connection was bad, called Vuma to have it removed and place it in a more stable position for connection purposes however the assigned service provider SDV has went awol. They don’t reply their WhatsApp and the landline number says number is no longer in service. On Saturday spoke to Keitumetse from Vuma Customer care who assured me she will log a call to move the router and said SLA is 48hours and to date I’m still waiting. Can someone call me to fix this ****
