No fibre

Have been without fibre for the last two weeks due to someone within one of your departments first dropping our 20mb line to a 4mb line and then canceling our line altogether. We've been trying to get it turned back on for the last week however cell c is blaming vuma for it not being able to turn it on and visa versa. This I completely unacceptable how the hell did this happen and why is it taking so long to be resolved. This is creating a detrimental effect on my studies as there is no internet at home due to an obscene and ******** error.
