Poor MWeb Service in Level 2/1 Conditions

I am struggling with my Mweb fibre at home for 5 days now. I have logged a call online but no one phones you back. The call centre is only available during office hours, yet we are in Level 1 conditions. I cannot do my work properly from home. What do I do? I have stopped being polite, since I am frustrated. This is such poor customer service, but my monthly instalment is on time. I cannot stop swearing at this!! How I deal with that?? How do I get help and customer assistance???????
