Pathetic service

Unable to use my ADSL since 28th November . No one provides feedback , contacted the call centre many times, 9 days after complaint was logged and than a technican was sent out. He couldn't fix the problem , the call centre agent called and i advised that the problem is not resolved. They will escalate. I called them today 15/12 and now being advised the same thing. The call centre manager Daneil is *********** and said that he just can just escalate same as what the agent can do, what's the point of having a manager???? I just want my contract cancelled at no cost to me for the terrible customer experience !!!! I'm so frustrated with these ********** that are *****ing my money with no service.
