Lack of customer feedback & failing to meet 7 days delivery promise

I placed and paid for an order online on 1 Oct 2019, after having checked avaibility of the colour I wanted. To date no delivery nor a response on follow ups, as their commitment was 7 days which has lapsed. It has been promise for feedback after promises but no delivery. I had informed them this was for a birthday gift of the 9 Oct, nobody seem to care.
