Century Link Misleading Info And Bills Increase Nationwide

When I signed up for internet service I was promise that if I sign up for a one year contract I would get a twenty dollar discount so instead of being sixty dollars it would be forty dollars a month. I receive my first bill it was sixty dollars, so I call back another rep tells me i couldn't get the discount unless I get a five year contract so I got the five year contract. One year later they start to charge me sixty dollars a month.  They kept charging more and more so i started to go back to look over my bills and it's been going up. I call them and they say i just have to pay for it because the previous rep told me wrong. My contract only last a year so after that they just kept charging more and more which I was not aware of. I was told I'm on a five year contract and after it ends my service will end but they just put me on another higher plan. I just want to keep my internet and pay the forty dollars a month but they won't do anything to what's been charge to my account. Do not use century link, worst customer service experience ever. They will get irated at you and get hateful, rep and company is very unprofessional. I don't think this company itself have any form of training.
