Cancels order with no communcation AND NO REFUND

I placed an online order (order number ********** 75) at Edgars on 17 December 2017. It was a Click and Collect order, which was charged to my credit card on 20 December 2017. I enquired yesterday as to when I coud expect to receive my order, only to be told it had been cancelled. I have receved NO notifications hereof, and have also not received my money back. Needless to say I am FURIOUS !!!!!!!!!! I was given a reference number ********** 1952/GO. I tried to call again today to enquire as to progress with sorting this out, only to be cut off on 3 occasions. This is dishonest, and I expect far better service from a store like Edgars.
