Argos has apologised after some customers suffered problems with home delivery and making contact with its customer service teams following Black Friday.

A number of customers reported delays with their orders, while others said they were unable to get through by phone to track their orders.

The Home Retail Group-owned business also had problems with its website in the run-up to and during the event.

A statement on Argos’ Facebook page, under the banner ‘Thank You for your patience’, said: “We’re really sorry for the delays in getting through to customers services.

”Our Black Friday event and new Fast Track delivery service have been hugely popular and are keeping the team really busy; we have added extra staff and they are working through calls and emails as fast as possible. Thanks for your patience.”

Separately, a spokeswoman told The Guardian that 90% of customers who wanted the Fast Track same-day delivery were offered that option and tens of thousands of deliveries were made. The retailer said the “overwhelming majority” of those deliveries had been made as promised.

Argos launched its same-day Fast Track delivery service in October in a bid to compete with rivals, including Amazon. However, the same month it issued a profit warning because of uncertainty around the vital Christmas trading period.
