Terrible service

Order items using the Builders warehouse online function. The order was placed on the 2nd of June 2020. The delivery date was the 17th of June 2020. I can understand that given the current situation. 17th came along and no delivery. I had a chat with the online team and they confirmed the items are currently been picked and delivery will still happen, It did not, on the 18th of June I contacted Builders again as no delivery was made. Eventually, after several calls the manager of the Northriding store calls me back and says...We do not have stock of your item. At the time of placing the order, the stock was available., He told me sometimes the system does not work the way it should, and the person that was tasked to pick the stock did not. I asked for a refund. I was told it will take 7 to 10 working days. Like really, when I paid for the items I did not inform builders to wait for 7 to 10 working days for my money. This is terrible service.
