No response for a refund

I ordered a pair of sunglasses from them over two months ago and it has still not arrived. When looking up tracking information, I just keep getting a tracking error. I have tried several times to contact them through different social media and either I get ignored or I just get told I can become an affiliate of the brand. I am trying to get a refund on my order and would like some communication from the company. On their website when you click on the contact details it gives you an email address that they don't respond to.
