Is it mandatory for my bank to endorse the DCA form before I mail the hardcopy to you?
Yes, all sections of the DCA form must be fully completed, including the bank’s endorsement, before mailing the hardcopy over to CAG. CAG will only process payment to a bank account supported by a valid and duly endorsed DCA.
Note: The instruction given in this form is valid only if it is received by CAG within 3 months from the bank’s certified date in Part II.
What types of payments will be made by CAG?
