Unpaid refund

Paid for a t-shirt in December and there was no communication from them until i enquired only to be told that they are out of stock at the supplier. I requested for a refund and since January i am being told that my refund will be processed. Every week i write an email to remind them of my refund with the last one being on 12 March and was told that it will be paid by the end of the week, to-date i have not received my money back. I don’t know why is it so difficult to process a refund. ****** of note, i won’t let this one slide, that’s my money.
