Paid but no products

I bought hair products from this business. They only sent me one of the 2 products I bought. I sent an email to ask for the rest and she was so rude(I can send the email if needed)and said they'll send the second bottle. To date, nothing has been sent and I bought these a few months ago. I tried calling and she wouldn't respond. I sent whatspp message and she blocked me. She won't respond to any emails also. I dont know what to do anymore
