Hi Lyn Gamer,

I today suddenly receive 2 message that my credit card have been used to purchase game in steam.

Total cost is JPY15000 + JPY20000

I'm not sure how and why did this happened, so i called my bank to block my credit card and check for the problem.

my question here is , how do i contact steam and is it possible to request them trace where did this transaction made? 

I did searching around but can't raise any question at steam support.
