Paid for an Item and did not Receive it

Order number: #90006 I ordered two Vapefly RDA's that were on special and some other stuff online. I paid for the order immediately and then had to wait two days for them to process the order. On the second day i got a phone call from a guy informing me that they only had one RDA in stock and if he could leave the money of the other one i paid for on my account. I asked for a refund for the out of stock item and he said it is fine i must mail my banking detail to him, he also gave me an email address. I did so only to find out that the email address doesn't exist. I then sent a message on the Vape King website and got no reply. I then phoned the Head Office and it took two days for someone to answer the phone. The guy i spoke to told me that he did not refund the money cause he managed to source another unit for me and it is on its way with the courier, he could not supply a tracking number and said he would phone me back with the number, he did not and no courier arrived at my place. I tried phoning again today, but obviously no answer. This is terrible service and the money for the out of stock item is probably gone. Right now as i am typing the out of stock item is still not showing as out of stock on the Vape King website and available for someone else to buy and end up with stock problems. In future i will rather support my local brick and mortar shop cause it is no use buying an item on special at an online shop if you end up paying for it double.
