Disappointing Service

I had ordered 2 items and paid for them on 14 December 2017. Delivery was expected before 22 December as these were Christmas gifts. I was informed that delivery was delayed because the supplier was out of stock. My issue is why accept payment if there was no stock. Delivery was then promised by 27 December and this did not happen with a further delay. Delivery was then promised by 29 December. During this period I sent several e-mails, receiving responses of apology but no constructive solution regarding delivery. I requested a Telephone number so that I could speak to someone but this request was ignored. I also requested details of the delivery company and this was also ignored. The tracking link also provided no solution. Today is 03 January 2018 and my last 2 e-mails have been ignored and I am no closer to receiving the items that I have paid for. This service is totally unacceptable and indicates total disregard for the customer because they have an established market. the service used to be good in the past, but I would advise customers to be wary of their delivery promises and I would review doing business with them in the future.
