Manicaa.com is a ****

I placed an order in December 2022 that never arrived. I tried contacting them and the telephone number on their website just rings. I reverted to email requesting a refund and I follow up weekly - and every week it is the same response - the refund will be in my account within 2 weeks. It is the 19th week of 2023 and still nothing. There is no-one to escalate my query to either - Manicaa is a ****.
