Oura refusing a refund after accepting their fault

I bought an Oura Ring 4 about a month ago. When I took off my ring before showering while taking it off my ring completely separated, after looking at it I saw similar people having cases and Oura having entire article about it so it is a known issue. I sent everything to Oura and was told that they will proceed with a refund, after that I discarded the ring because the battery was exposed and i’m not gonna keep something faulty in my house. Now, they are requesting me to return the ring back even though this was not the case when I was talking to Leon before he escalated this to Blake. I am now forced to just take the replacement ring even though I don’t want to, and I explained to them that I don’t want it due to it inaccurately reporting my heart rate during training, inaccurately registering my heart zones during training and gaps in my sleep tracking (all was mentioned to oura). Overall horrible experience and I regret that I recommended my collegiate team to get those rings, now that I know how Oura really is I won’t tell my teammates to buy this anymore.
