Worst Service Ever

I urgently need someone to advise what i can do please.

I have fibre (mplain fibre) vuma reach my service provider is MWEB!

However my line is active but my landlord also app**** and it is showing active but they dont have a router nor was anything installed by them.

So my account is on their name hence the confusion.

I am ugently looking for a direct email address or contact number for a supervisor or anyone in management at MWEB pls.

I have called the *** and the other number like 100 times. They keep on saying someone will call me back but no one does then I have to call daily and explain the same thing over and over to a different person.

I really want this sorted as it's been 4 months now and still nothing.

ITS SO FRUSTRATING EVERY MONTH THEY GET THERE MONEY BUT DO NOT ASSIST WITH ISSUES.
