BEST YOGA STORE Tried to cancel over and over

I made a purchase online from THE BEST YOGA STORE for yoga pants, I didn't know the clothes were coming from China.

The store says its American designed it never said merch comes from China. I found merch here in the USA and much cheaper. Tired over and over the next day to cancel and my order hadn't even shipped yet. i have an email exchange and they never acknowledge me trying to canceling she just kept saying it would come soon.. and the date was weeks away, I said I wanted to cancel and not once would they acknowledge, Yesterday the product came and they will not return emails or calls no way to get a person to return product to get money back. I have not opened the package and am trying with emailing over and over asking for an address to no avail will I even get a return email at this point and no person to answer their customer service emails or calls.
