US-based e-commerce major Amazon has faced the wrath of its customers after the company’s website experienced some technical issues on Prime Day.

The technical glitch created problems for customers looking to complete their online purchases during the discounted-shopping event.

The issues were reported to have been faced by customers in the US and UK.

 The retailer said in a Twitter post: “Some customers are reporting difficulty with checkout. We're working to resolve this issue quickly.”

While some customers reported problems in adding items to their cart, others were unable to access the site to shop.

The one-day sale for members of Amazon's $99-per-year Prime subscription service was expected to fetch nearly $1bn in sales, Reuters reported, citing a study by Citi analysts.

Amazon devices such as the Echo voice-enabled speaker, Fire TV and Fire tablet were sold at huge discount during the sale.

The company had also encountered technical snags when it launched the Prime Day event last year, the BBC reported.

It sold over 34.4 million items on that day, surpassing the goods sold on Black Friday in the previous year.

Other sites including Argos, Boots and Tesco had faced similar problems during last November's Black Friday purchases.

Last month, Amazon launched its own food delivery service in the UK.  Under the new service, the online retailer initially offered over 130,000 groceries to its Prime customers in Central and East London, including thousands of fresh produce, dairy and bakery items.

The service was offered to Amazon Prime members for £6.99 a month with unlimited delivery for orders exceeding £40 following 30-day free trial of AmazonFresh.
