Supersonic midstream

I have been without internet for the last 2 weeks .your technicians promised an appointment at 9.30 , 2 mondays ago but never arrived .many calls daily with whats app being ignored i am still without internet, i am an essential user as i work for a financial institution and must work from home i cannot do this without internet. Where is the promise that your management made to the HOA of Midstream,poor call centre response, poor technical support I want this matter sorted out ASAP .
