Cancellation after payment poor service

I’m really angry and frustrated, l have been a loyal customer to the business after a month an item in my wish list today it was available after I got a notification I did my purchase successfully then I get a message after 2 hours that my order is being cancelled. I had to call to get the reason not even an email my refund is been processed who said I want a refund? I was happy that I finally got my size after the waiting I’m so done this is not fair at all I will expose the business for this 💔😡😡😰😡😡
