Complaint Review: Qchex

PLEASE HELP!!!! I just deposited the check into my bank account for $5700!! The bank teller said it looked fine to her, but my friend suggested I look this company up online. I just did & found these postings! I am near Brunswick Ga Jeannette- please contact me asap! Should I go back to the bank & try to stop deposit or what??? If the check clears to my account- do these people then get my checking account information & do something with it??? I sold two DIAMOND RINGS- but I will not send them until I know whats up! This person keeps emailing me to see if I got the check & wants me to mail the rings now- I won't until I know everything is ok. Please give me some advice!
