Out or in stock....confused!!!

Last week Thursday ****h of Feb) I placed an order, only for it to be cancelled on Saturday due to it being sold out. Voucher took forever to come through, so I could not buy item over the weekend. I saw that the item was still available online, asked the Chat assistant if item was in stock, got a positive response. Today I get a call to say that item is damaged and was the last one in stock.<br> <br> Can I please get a refund in cash as I have to go buy elsewhere. The voucher won't assist me in any way.
