Online order not processed two months later

One the 27 November 2015 I ordered a bicycle cassette online. I proceeded to make payment with the usual name and reference that I've used in previous online purchases. Two weeks later, after receiving no feedback I sent an email requesting feedback and received no response. A few days later I went into the store personally to inquire and was told the stock is in Holland and they will inform me when to collect. On the 20the January 2016 after receiving no feedback I again went into the store and was told that all the stock had been sold and the price is significantly higher now. I requested a refund as it was clear that I was not going to leave with the goods I bought at the price I paid.
