Worst online shopping no refund rude agents

I placed an order on the 17th Of July on their app for a washing machine and I paid only to get an email Friday that the machine I paid for is out of stock false advertising I paid them to keep my money and not return it. I spoke to an agent ncwabisa who was rude and told me to wait 14 days for their incompetence I need a washing machine asap and I gave them my money to just keep it for false advertising she ended the chat without contacting head office that 5 days has passed as stated on the email I will receive my refund. Do not place orders on samsung application they don’t update their system they allow you to pay for something they don’t have
