So long story short i sold rims to some guy around 3 months ago. They were near mint and came with tires that were bald in back and perfect tires in front... He had his car lowered and fenders not rolled and the rims he bought from me were rubbing.. So just today he somehow has my number and txts me saying "he wants his money back and hell give me my rims back because he scratched the rim and the front tires have massive camber wear and thats not what he thought would happen or some BS" saying he remembers were i live and all this BS
all i could tell him was leave me the **** alone and dont come anywere near here... and your not getting your money back because 1 its been 3 months and 2 you ****** the rims up yourself...

What do i do? change my number? what would you do? hes one of those worthless mexican dudes, im not scared of him but i dont wanna be harassed since my family lives here aswell...
