The dental office did not issue me a dental receipt, can I still claim my reward?

The dental office will still be able to give you a copy of the receipt upon your request.

If you are still unable to obtain a dental receipt, you may send us an insurance document (EOB) instead to show that you’ve attended your appointment.

There you go - you may proceed in submitting your claim-- how?
