No delivery on items purchased online

I ordered 3 items the morning the online sale started to avoid disappointment (***). I spoke to the operator before checkout to confirm sizing. I also spoke to the operator on the Monday and received a confirmation of order notification. At no point was I advised that the items were out of stock. Then on the 31st I received a notification that there was no stock. I contacted the online shop on the Monday and the operator confirmed that there was a stock shortage but that my order was intact and that I would indeed receive my order in due course. Then I received an email on the 4th advising me that some of the items were available and some not. Email in response remained unanswered! Another email on the 7th advised me that there was a shipment delay. Today I received an email to say that they were sorry for letting me down on the order and were unable to locate items at their online store and that I will be refunded!<br> I am left extremely disappointed for not receiving the items ordered as I need to now spend more money to find a suitable replacement and for being given the run-around. This of course also raises some concern regarding their online purchasing process.
