Very bad service from Vox Telecom

Very bad service, since half December and whole January no Internet Service from Vox Telecom. They are not prepared to even Credit One month to compensate for the loss of Internet connection. Several routers and a SIm card were replaced but as per Toaday the issue still exists. Dropping of the connection whilst in the middle of a process is extremely annoying. Vox cancelled my account which I never requested, they made me sign a new contract to get connected again. Now I find on the statement that I have to pay for the ''öld''contract and the new contract (I did not request) double. I am a pensioner with low income and am not able to pay these 2 amounts. I have spoken to many technicians and they also do not know what the issue with the router is. What am I paying for?? Its rediculous!
