Very bad service

If i could rate minus 10 it wont be enough. Ive been with this company as my ISP for years now. Since they became Herotel Breedenet there internet went down the drain. I've send emails for days now. I got a answer 3 days back with a screenshot that I'm using all my bandwidth and 5 min later there are a problem with there towers. A day later a message that its sorted out, but my connection tests a quarter of what I'm paying for. Now nobody answers my emails and im still paying for the full package every month. Ive revered a lot of people to them and I am so sorry for that, because at that time there where service, but now nothing.
