Internet Providers Nightmare in Netherland

Long Story Short on December my Internet Service with T-Mobiles was cut off because a Fraud Person Created a new account in my address.   Anyways I was away on Holidays when I came back in January I realized my internet was off I called them and they told me above reason.   I was asked if I was going to be penalized for the remaining of the contract and I was told No because it was not my fault (But At the end they did)  but in order to get my internet back I need to wait 15 Days for them to reinstall.
Looking at my mail I found a KPN Letter with the Modem BOX in a different name. So I contacted KPN and they told me their version of the story. I was told I can sign up with them and don't get cut off of the service because the service was already in my house. So I Did .
In Mid January I received a Bill from T-Mobile for €200 for the remaining of my contract. When I call them again I was told that the only way to received my money back is signing up a new contract with them. When I called KPN I was told I was not able to cancel my new contract otherwise I will be charge for the Remaining of the year even though I only been with them for 2 weeks.
OK so now my Question. There is anything I can do in this situation to get my money Back?
I can't believed how easy was my service was cut off without my authorization and at the end I was penalized for that.
