I noted that the OPA showed Casino Towers as an approved site. Decided to open an account. I checked the OPA site for the how to on collecting the 20% bonus and I found nothing listed on the OPA's page about that. So went to Casino Towers and clicked on button that said 20% for OPA member. It does not tell you the referral code to use here either. Said OK who cares, don't need bonus, not going to open the account with much anyway. I opened an account and deposited and played. Nice place. Enjoyed the slots a lot, usually never play slots, but these were fun, good payback. Went to deposit again and it wouldn't work. Went to find CS and the link on the front page takes you nowhere. The link on the bottom of the page that says LIVE 24/7 well that one is a dead link. So please, where is the CS unit here?
