Where is my order or refund? RUDE AND UNPROFESSIONAL COMPANY

I ordered a necklace from them on the 19th of November 2021. It is now the third of March and I have heard nothing about where my order is. I followed up with them on 3 separate occasions asking about when to expect my order and was given stories about the supplier delaying the shipment. I was told there will be 1-2 weeks delay and that time frame has long passed. Now, I am requesting a refund and the consultant has been ignoring me and has responded rudely to my concerns. Very unprofessional service. Do not buy from them unless if you want a similar experience.
