Why am I paying for something that doesn't work

I had a fibre line installed at my house last week - it worked for 1 day..... I've spent hours on the phone trying to log a call / get someone to assist me but only got empty promises of a call that would be logged / ref that will be sent - BUT NOTHING HAPPENED!!!! I am unable to log the fault online as your system doesn't allow for fibre faults to be logged online. I've sent e-mails to the so called fibre department - NO RESPONSE!! This is totally ridiculous! O and your call centre staff keeps on asking for the phone number of the fibre line - and when I explain it is data only - no phone number is linked to the acc they treat my as if I am stupid and keep on insisting for the voice phone number. Your staff clearly needs URGENT training and I need someone to call me today still to get this line sorted.
