Refinance Car Loan

Question by simple:
Wells Fargo gave a automobile loan to someone in a different say using my social – what can I do?
Over a year ago I made a phone call to Wells Fargo about something and the lady asked if I wanted to refinance my automobile loan. I said my automobile is paid off, I do not have a loan on it, and I went on to find out that someone in Kansas (I live in Los Angeles) has a automobile loan using my social security number through wells fargo. It was clearly an accident – their phone number including the area code exactly matches my social lol. I went in person to the bank which is what the auto dept the lady transferred me to told me to do, but at the bank they said they can’t give out any info on another client. I was at the bank recently and again was solicited about my automobile loan – 1 1/2 years later it is still there after I have told at least 5 people at Wells it’s not mine. What can I do??? At least they’re making the payments on time so I think the people have no idea the loan is on another person’s social. Please help. Oh, and it’s not on my credit report, prob. because the name is different than mine.
I can easily call the people up and their phone number is simple to remember considering it’s my social, but then I am scared they’ll stop making payments on the automobile maybe or use my social for more credit or ? seems to risky to inform them. And I can’t dispute with credit agency since it’s not on my credit, and wells fargo will not release any more info on it to me since it’s not under my name!!
I’ve since bought a home and had my report pulled many times – it is definitely not on my report, but i get solicited about it every time I call Wells F. The very first time I found out, the operator was very sympathetic and nice, told me it was a brand new automobile and how much the loan was for and so on. I did call the police now that I remember, and I forgot what reason they told me that it’s not something they can help me with. I called several police stations they all said the same thing they can’t help me. I guess I will just ignore it and hope nothing more happens with it.
That very first time I called, the operator said my social is the first 9 numbers of the phone number they have listed for “me” under the automobile loan (starts wtih 620). The loan was for 30 something thousand.
