Was sold a car with the wrong miles

I bought a lexus is250 a while ago with low mileage. On the odometer and in my certificate of title the mileage reads 93k, but when I was trying to sell my can I ran a carfax and it says that the actual mileage is 160k. Im not sure what to do. Any suggestions would be greatly appreciated.

if its been over 90 days not much you can do. especially if you bought it from a private party
