Considering the gold farming they are dealing with and reports flooding in about those and the CS agents getting flooded with other things that needs to be dealt with...Im guessing your report is in the system but its 1 of maybe a 1000 they got over just a few days about various things.

I wouldn't take a lack of response or action as they wont take action ..just understand they have many other issues with higher priority to deal with 1st.
