Bad and dishonest service

On Sunday I put through an order (***)on Woolies Dash for delivery between 11 and 12, at 11h53 i received a late delivery notification and the driver tried to contact me after 13h00 for delivery. A lady by the name of Noma contacted me on whatsapp on 076 344 ***9 and said driver did not have unit number which is on the app please note. The groceries were not delivered and Noma advised a refund was processed. Today still no refund and Noma blocks me on whatsapp as i said she needs to sort this out given that the groceries were not delivered, she advised refund processed and also is aware of the issue because they marked delivery as done on time on the app. Why we working with dishonest people in a big company like Woolies and receiving such bad service? Really disappointed in the service received from Woolies. Refund me! Noma is giving you a really bad name and has terrible customer service skills.
