Although your young they can do a lot of damage to your credit files. I suggest you go make a police report, pull your credit report and immediately dispute any problems you see on there, also call the head office of that supermarket chain and notify them of the fact that someone might be fraudently using your SS number.

Good luck but I suggest you move on it fast and stop any possible problems that can come up. Bad credit follows you for a long time and can even impact you getting a job or insurance.
