Wrong products and NO refund!

If I could I would give a negative score. I ordered parts for my Xiomi robot vacuum. Actually ordered two sets of the parts. It took like two months to deliver. When it finally came, the parts did not fit my model. I sent it back as I was advised. I still have not received my money back. This is the most UNreliable online store. PLEASE DO NOT WASTE YOUR TIME OR MONEY! Products aren't what they are set out to be and you will never see your money again!
