What is wrong with MWEB fixed LTE

I am somewhat disgusted with how MWEB deals with technical problems. Have a fixed LTE package that we got through them and have literally enjoyed 30 minutes of decent internet and then nothing since last week Tuesday and they are still (finding/fixing) the problem. Sure there must be a better way then to call the call center as one wastes your airtime waiting only to speak to someone that does not seem to know exactly what is going on. Please,please,please,this is now really painful. What is the use of switching service providers to be stuck with nothing in the end.
