@RRRRefundHi sorry for the inconvenience, I believe it maybe out of stock at the moment.
If some come in stock they will send you a dispatch email confirming that your item has been sent. I hope you did receive a confirmation email from them when you purchase it?
You can call the customer service for support, the best time to call is 8am and try the number ending with 4005
