Im a jr and my fathers using my SSN

I first finded out about this approximately 5-7 years ago, when I tried to order comcast cable and they told me I owe over a thousand dollars for not returning cable boxes. I knew it was my father because the service was linked to his mailing address at that time. Comcast threw it out because the account was open when I was approximately 16 years old. Approximately 4 years later I did a free credit report where I saw a lot of fraud accounts and general information that I knew nothing about. For example, the credit report had both our ages and just about all mind and his mailing addresses. One day I randomly decided to call all the local ulity companies and peco energy told me that someone was currently using my SNN for service. I knew it was my father because the service was linked to his place of residence. Currenty I have gotten serious and contacted all 3 major credit bureaus and all the creditors/collection agencies. Only one collection agency reply correctly by deleting all 4 fraud accounts they had, whereas zenith acq just made updates. Zenith has 2 fraud accounts that I believe my father is reponsible. There is 3 fraud account own by verizon; I contacted them and they wanted information I can't provide such as, home or apartment lease, or a ulity bill. I am 22 year old college student.

Is there anyone who has decent useful advice adn this particular issuse.
