Hello, I deposited with a medical/flex savings account debit card. After a few too many deposits, they automatically flagged it in there system and cancelled it without knowledge. I just received an email from the voucher company and they canceled and refunded all transactions. I did not order this and am not trying to scam anyone. I will repay the book, via bitcoin or other method if need be, even before they replenish my account. I don’t blame the book at all but is this reasonable for me to pay the book back or is it risky?
