No service- Not even callback

Guess you guys dont care about your existing customers. I've logged a fault 3 times now. 1st 2 calls was just ignored and tickets closed. Thought i'd phone in last night and asked Vox to phone back. That was at 19:07. No one bothered phoning me. Got a message at 23:44 saying if complaint is about callback that I should just phone back again. Whats the use of having a callback feature if it doesn't work. I'm still experiencing issues with my line. It takes ages to open website. I'm streaming movies but last few days unable to watch tv because of the fibre. Looks like I have to lodge a formal complaint to get service from vox. If this is the service I will be cancelling and going over to another isp that will actually help and value their customers.
