No remorse on error made

I Overpaid my woolworths account by R4000 and my bank referred me to Woolworths for a refund. I logged an online request, no response, and sent an email, no response and then called. My ****en surname required updating and I sent all required documents and telephonic confirmation was received that all has been updated. Email correspondence received all details updated and refund would take 2-4 working days. Today is day 5 and no refund. I call to follow up and am told the bank confirmation surname does not correspond with my account details. The details ws not updated and I will need to wait another 4 working days. I am patient however this is just unacceptable. I need this cleared and refunded by tomorrow before close of business.
