Shriram City — Loan fully paid but asking for arrears after 10 years

I took a loan from Shriram Finance 12years (2011) back and had paid fully in 2years. Now they sent a message to loan guarantor saying that there are arrrears on my loan and i need to pay Rs.11294 on loan account number NRSPRPL06050007. I didnt get a single information all these years regarding this and sudden out of blue they sent a message to immediately pay the arrears. I am not sure if this is true or fake and also why didn't they inform all these years and now asking for hefy amount after 10years. Please take it seriously and resolve my case.
