I had two emails from these and didn't know whether to respond, one was from bingosecurity@cassava net and the other from casinosecurity@cassava net, the bingo one had an amount they apparently owe me but the casino one didn't state an amount, I called the number 08002794569, they told me to reply to each email as the may be two separate amounts to be paid...I hope so! The person on the phone also confirmed the emails to me legit.
