Want my money back! Unhelpful support team

I ordered a Jumpsuit from spree on the 10 of October 2017. The item was delivered and did not fit upon which I requested a return (return # ********** 09-1) and asked for the money to be refunded into my bank account. The item was fetched and on the 16th of October I received a message that the refund has been processed and "my money was on its way" and this should take 3-10 days. 2 weeks later I still haven't received a cent. I have contacted their support team on numerous occasions and they keep telling me that my refund has been processed and to check against the date I made the purchase. I have obviously checked and checked and still nothing. I'm so disappointed. Spree is so quick to take our money but you have to go to hell and back before you get it back. I want my money please!!
