Review Bad experience

We're loacted in the Klein Waterberg area and we have a Fritz box 7270 and pay per month. At the begining the internet speed was fantastic but now I can't even test my network speed. Other residents in the area are also complaining about no internet connection. I've bought a new modem and there is still no internet connection and it's getting worse each day! Why do we need to pay for something that we don't even have? When will someone fix the this problem? I work from the internet everyday. This can't continue.
