Defective products and poor service with returns

I ordered a IBIDA M3 Fitness Tracker Smart Sport Band - Black which was delivered on 07-06-2021 After the faceplate fell off, I returned it for replacement on 03-07-2021. I have since seen on your website that the return was declined on 10-07-2021. I was not personally informed about this and only found after I tracked the return. What does that mean? Does it mean that I paid for an item, returned it when it broke and will not receive a replacement? On 23-07-2021 I received a response that the issue will be resolved Seven days later nothing!
