Direct Debit means:
التحصيل المباشر
"Direct debit or direct withdrawal is a payment system that allows an organisation to instruct their bank to collect varying amounts directly from customers' accounts, using an electronic funds transfer." or "A debit made to an account for payment; generally refers to the electronic and direct method via ACH."
unpaid refers to "Direct Debit" not "fee", as the bank failed to collect money due to lack of funds:تعود على "التحصيل" و ليس "الرسم" لأن الدائن عجز عن التحصيل لعدم وجود رصيد كافي
