Zoom fibre has a very bad service

My network has been down for more that 10 days , even today I am still not connected , everytime I talk to them on the phone they tell me about their 24-72 hours SLA. Today I received a message that I must make payment but they didn't notice that my line has been down. I have been waiting for ativation after the faulty router was changed even today I am still NOT connected . Zoomflex failed me disimmally.
