Kmart has apologised to customers over lengthy delays in shipments, as well as virtual queues to visit its site.
In an email to customers, Kmart retail director John Gualtieri said the retailer had experienced unprecedented demand in eCommerce orders.
Stores at Brandon Park, Victoria, Top Ryde, New South Wales, and Caboolture, Queensland, are now operating purely as online distribution centres in a bid to service demand.
“It has certainly been a different type of Easter for us all, and I feel it's vital to acknowledge and sincerely apologise to our customers who have yet to receive their online order or continue to experience delays reaching our customer service teams,” he said.
Gaultieri said “various factors outside out control” were responsible for the issues, which included a delay in customer service enquiries.
"We've been overwhelmed with the volume of orders over the past few weeks and stock availability has been impacted; making it difficult to keep up with our customer needs."
