On & Off Service!!! LAME Excuses!!!

I pay for a FIBRE line that is supposed to be stable, but since I've joined EASYWEB, I have had NUMEROUS breaks in service!!! It ranges from drops in speed, being constantly disconnected or NO service at all! They blame VUMATEL, but I do not care, as EASYWEB is my Service Provider! I complain at least 5 to 10 times per month! It is a problem at EASYWEB, because every time I complain, all of a sudden my service is back, but only for a while! I've NEVER had so much hassle with LTE! They did however double my speed for the same price, but it means NOTHING if I don't have service! I've now seen that other people complain about the same issue! WHAT IS WRONG??? CAN SOMETHING BE DONE???
