Extremely bad connectivity - Fibre

For the last couple of days I have been getting really poor connectivity to my Fibre internet. MWEB customers surely have endless problems, when you call them, there's always 30 plus callers holding on and it aint a toll free number so you are paying high rates and sometimes you can hold on for more than 10 minutes and still dont get help. I cant even find an email address to complain, you have to phone. Im paying for a 40meg line but hardly get 1meg. Please can someone who is competent please address my problem and fic it. MWEB you are pathetic!!!!
