BAD Online Purchasing

I made an online purchase for a washing machine. When I made the online order and payment their website indicated the item was in stock and that delivery takes 2-5 working days. After lodging a complaint, I was contacted on the 5th working day and told the item is out of stock. HIGHLY unprofessional and not acceptable. Emails are not responded to and their phones just ring the whole time... worst online buying experience.
