Sneakercouturesa bad treatment

I ordered sneakers from Sneakercouturesa and paid the full amount on 24/03/2024 and payment was confirmed and a promise to deliver within 3-5 days, but to date I still haven’t received any update from Sneakercouturesa and all attempts to contact them have failed. The way Sneakercouturesa is conducting their business is really unprofessional and where I am sitting I am asking myself if it’s a ****. Can I be assisted with the contacts of Sneakercouturesa to get my refund.
