Utsav Fashion — I would like to complain about how falsely the website is advertising about their shipping

I placed an order on Dec 3rd, one of the items from the order promised to be shipped in ten days ( ready to wear), so the only reason why placed the order was to get one of the item before Dec 25th, so I can wear it for Christmas. I had to email the company multiple times to inquire about the product and each time they would come back repeating the same information that the item has been delayed by the carrier. When I didn't get the item on Dec 24th I had to purchase another item from the local indian clothes store and told the Utsav fashion gazzilion of times to cancel that item and process my refund if I do not get my item before Dec 24th, but instead of acknowledging my request they are kept on sending me the same email over and over again. They have not only ruin my event but also have wasted my time and given me mental stress. All I need is to get my money back for the item that did not fulfil what their website promised. I am I'm at to wait for the other item as it did not have any prior promises on delivery and shipment. the order numberthe order number is MU[protected]. I will complain and share my explain anywhere where I have to.
Regards.
