Complaint against online tailoring boutique

This complaint is against an online site tailorboutiques.com. I contacted them online. They have a Whatapp number -8448448089. I submitted my dresses to them for stitching . 5 sets for stitching . And 2 alterations , worth rupees 10,000 for stitching ones and alteration ones were 20000 . I was supposed to get my delivery on 11th November . They didn’t . And now I am texting them for past 48 hours there is no reply from them . They are totally gone . There is no contact number . Only a Whats app number and they are not replying . I don’t know if this is a fraud website or what . Pls help
