There are a couple of possible reasons as to why your free spins could have been removed:
1) If you have requested a withdrawal, any free spins you have remaining on your account will be lost.
2) Free spins expire within 48 hours after being credited to your account. If you haven’t used them during this time, you will lose your free spins.
You can check our promotional terms for more details. If you feel the above doesn't explain why your free spins have done, just get in touch with us through our 24/7 Live Chat and we'll check this for you.
