Worst Online Shopping Experience

I placed an order on the online store on 1 July, it has been such an uphill battle to get this order. three quarters of the order was delivered after two weeks of me waiting for it and then me following up with the customer service. If i did not email them or call them I would never have known what the hold up was, the product I order was out of stock and they were trying to source it. I was informed there was only one product that was out of stock, I said it was fine they should refund me for it. Upon receiving my delivery I did stock taking and found there was items missing, I called the customer service and informed them, I emailed the customer service everyday since and to date there has been no resolution. I informed them I do not want the products anymore they should just process a refund for me. Its been a month since I placed my order and I have not received the complete order or a refund for the missing items. This shopping experience has been the worst I ever had, and i have shopped previously on other online stores!
