Why the waiver exists
The waiver creates an explicit record that you understand Direct Deal operates with reduced IVOTIA protection compared with escrow.
It is there to prevent confusion later about what the platform can and cannot protect after contact details are unlocked.
Refund expectations
The unlock fee is generally treated as a delivered access service once contact details have been revealed.
If you believe there was a technical failure or duplicate charge, contact support with clear payment evidence so the case can be reviewed.
