Poor service received

On 19 August I placed a Woolies Dash order but my order was not delivered because the driver claims I did not answer his calls but I did not have any calls from the so called driver. Nevertheless, my order was returned to the store and I was told that the money would be refunded to my card within 7 to 14 working days. Last week I followed up on my refund, only then was informed that Woolworths was not able to refund back my card and I was given the option to either send proof of my banking details for a EFT or a refund via gift voucher. I opted for the refund via gift voucher but till today, there has not been any voucher sent to me. Whenever I follow up, I get told that it takes another 3 - 5 working days.

I am so disappointed in this poor service received and the lack of urgency to refund my money. I am constantly calling or emailing but response times are so poor and lack of communication around my query is appalling.
