Pathetic poor service

RCS has been debiting money from my account for almost 2 years now without my permission. I asked for it to be closed and cancelled but that did not happen. Everytime someone calls they never assist. I spoke to a lady today and after I told her everytime someone from rcs calls I never get assistance, no ody picks up when you call, she then also hung up the phone and did not call me back either. I want my money back that was debited without my permission.
