Online order icomplete

We went to the silver lakes branch to buy a item in store. We were told that the product can only be ordered online. We made a online order of 6 ifems the order status kept saying in progress. When i phoned to find out what the problem was i was informed that 2 of the items on the order is not available and must be ordered. I then suggested that they cancell these two items and just refund them. I was told that the rest of the order is ready for collection and that i can just go to the silver lakes branch to fetch. I immediatly drove there to collect. On arival i was informed that the order is not yet picked. They told me they will do it and i can return in 15min. On returning after a half hour i was told that they are still busy with the picking. 1 hour later they informed me that even though their system says that another product (3rd item) is available they can't find it. Again i told them to just cancell that item. After another half hour they brought the three remaining items. We are told that the money will be refunded as soon as it was processed. I wonder if that will ever happen? I will never order online again and suggest anyone thinking of doing that to never do.
