Online shopping ****

On the 9th of March, I ordered and paid for two dresses from Everything Stylish. Their website and the confirmation of payment email stipulates that it takes 3 - 8 days for delivery. On the 10th March I received an email from Everything Stylish stating that my order has been processed and will be shipped within 3 - 10 working days. On the 18th March I had not heard anything from Everything Stylish and requested a tracking number. On the 19th March they responded and stated that there will be a delay and that they are out of stock. On the 20th March I requested a refund as they were for my maternity clothes and since they cant give me a delivery date, I would rather just have my money back. They responded the same day to say that they have already ordered from their supplier and that I would have to wait until they receive stock. I then again pushed them for at least an estimated date. They merely stated that I will get a tracking number once they have received it from their supplier. Since then they refuse to refund me or give me any other info. I have stated that I no longer want the clothes and I want a refund and they are not responding.
