Very bad service

I ordered an Intelligent Health Bracelet in December, it was delivered in January but was not working, I returned it at the end of January and requested a replacement. I have sent numerous follow ups and requested that the item be sent to a different address - to date no one has responded to my queries. I ordered something else in the meantime which has been delivered but the items were not even wrapped nicely, the boxes were damaged. It looks like this company does not care about customer service at all.
