Horrible service!!!!

My internet has now been off for 3 week. I've logged multiple faults, I've troubleshooted with at least 4 people and nothing is being done to fix the problem. Every time I log a fault nothong happens, no one gets back to me and when I follow up I'm told that the fault has been resolved. Explain to me how a fault can be resolved if I still have no internet??? The last person I spoke to refused to help me because I need to do another test with the ONT cable or I cannot be assisted. Explain to me for the love of God why do I need to keep doing tests but no one is fixing anything. This is the worst service I've ever received from any service provider. You just blatantly refuse to help unless I do your job AND refuse to send someone out to help me. What am I paying for??
