WOOLWORTH NEED TO DO HOMEWORK ON ONLINE BUSINESS

Refer order o***. Bought Duvet online 21 November. It was delivered 28 November. However the duvet is suppose to have/include two pillow cases which it did not have. The local branch needs a tax invoice to even listen to me. I send e-mail to online on 4 December . First they said warehouse needs to investigate. Problem still not solved it is now 17 December. A Mihchail said I can download tax invoice from my online profile but the only info online is that of the order and the delivery.
