NO REFUND AND NO ONE TO ASSIST

I ordered and paid for items on Spree online service, a week after I followed up and my payment was not processed, they processed the payment after I made the call, it was a week before Christmas when I made the purchase therefore the delivery was delayed, I tried to have them speed up the delivery as the delay was on their side but instead my order was cancelled by the consultant I spoke with against my wishes, I called back and spoke to Tracey who processed the order again but unfortunately 2 of the items were apparently nor available anymore, I asked her to have the 2 available items delivered to me and to have the refund paid back for the other 2 that were not available, subsequently the 2 items were delivered and I sent her my banking details for the refund to be paid back on the 22/12/2017 and I was told payment would be made within 48 hours, to date I am still waiting for my money, I have tried to follow up, sent emails but no one has gotten back to me. may I please be assisted and have my refund paid back to me as not only was this whole process bad for me for someone's incompetence but now I am made to pay for items that I did not receive and was told were out of stock, I doubt if I will be doing business with Spree ever again after this terrible experience!
