Woolworths online took our money and never delivered our goods

Currently 8 months pregnant and not wanting to expose ourselves to the new variant of the corona virus my husband and I forwent the opportunity to spend Christmas with our moms and stayed home. We ordered from woolies online delivery for our Christmas lunch but IT NEVER ARRIVED. Despite numerous attempts to contact them on various platforms and finally getting hold of them with a promise of a refund, a month later this has still has not been processed!
