Day 3 -refund still not been processed

I swiped my debit card to make payment for the bed, but when I requested a refund I was asked to come into the store with a copy of my bank statement to prove that I am the account holder of the bank account they were going to re-imburse the purchase into. I don't understand why no proof was required for the debit card that I swiped.After the refund was emailed, I was assured by the store that the refund would be processed by the following day. I called yesterday to follow up only to find out that the store submitted my refund to the incorrect mailing address and has to re-submit. When I contacted the refunds department, I was told that because the refund was submitted after 10am, their banking was already done and they could not process any more refunds. Dorothea (refund admin jhb HO) then said that she can only send the paperwork to cpt HO the following day for processing as banks had closed when we spoke (4pm) and they will take another day or 2 for the funds to be process.I don't understand why an internet or eft payment was not done to me? Or why the refund request went from the branch to the jhb head office and then to the cpt head office with the request taking 1 day at each
