Why was my Interac withdrawal cancelled?

Why was my Interac withdrawal cancelled?

If your payout request was cancelled shortly after it was requested, it mostly likely indicates there was a mismatch between the last name we have on your account and the last name on your Interac profile. As such, we are unable to process your payout.  Please contact your bank to have your last name changed or do it via their online banking. You will need it to match what's on your Fallsview ON Casino Account.
