My ADSL has been down for Months I've been paying

I logged an incident with the ISP (Cybersmart) about 4 months ago of my ADSL not working and I never stopped paying for the account, the incident was closed without a resolution and no reason was specified. Since then they reopened the incident but I get empty promises from these people. They reopened the call every time I phone Cybersmart these guys are surprised and end up making promises of phoning which they never do. I don't they know why they do business cause clearly the have no idea how to work with customers. <br> <br> I have been patient with these people and now they are really taking me for a fool. The consultant i was talking to just dropped the phone and when I phone back she was out for tea according to her colleague. This is extremely disappointing.
