Incredibly Bad Service

My SADV landline has not being working for the whole of last week. My husband and I have been calling them to repair the telephone. And it is still not repaired. I am tired of calling these people and explaining to them what the issue is. When I call I get a bad attitude and arguments on why I am frustrated instead of the telephone being repaired. We have also planned for them to come to my home and that did not happen. This is frustrating and I would change my service provider and pay someone else for a better customer service.
