Temu Y18 Smartwatch Stopped Charging After Normal Use

I bought a black Y18 smartwatch this year from the online platform Temo. After some time of normal use, the watch suddenly stopped charging about two weeks ago. When I connect it to the charger, it does not respond or show that it is charging, and because of this it has been completely off for about a week. Since the product is still quite new and I used it in a normal way, I believe this is a quality or manufacturing problem. I request that my watch be replaced with a properly working one as soon as possible, or that a suitable solution be provided.
