I receive txt messages from my bank when there is any transaction, it's currently 12am and this GRC vitamins scamming company just charged my checking acct, I have no clue who they are, how they got my acct number, I definitely know that I didnt order anything from them, I tried to call this company at the number listed below on this complaint page ( thanks for the number btw ) and it went to a recording that they are closed and to call during business hours, so, how, at midnight, if they are closed, are they able to charge for so called vitamins i didn't order?? How do these people get our acct numbers?? does anyone know ?? help me out here i dont know anything about how this works or what to do about it to avoid this from happening in the future! Thanks, D
