Battery life of one week - Ring Video Doorbell 3 (not hardwired)

Purchased in April 2022, UK-based. Installed by front door, works fine, 3 metres from the router, no connection issues. **Battery life is one week - not the "months" quoted in the advertising. Resolution needed by Ring to sort this.** I have contacted customer service via phone to report the battery life issue and request a resolution. I was asked to reset the unit. The rep also did some "changes" in the "backend" of my device with no specifics given. All settings have been adjusted to be at lowest battery usage as confirmed by the rep who was granted access to my account. I was advised to fully charge the battery and see if it improved, but if not he would send me an email which i could reply to for further help. Email was received, the problem remains, but my reply to the email has not been acknowledged or replied to even by an automated response in two weeks. **Ring customer support - please advise how you will contact me to resolve this, or i will be requesting a full refund as product does not meet expectations as advertised. Happy to try a new battery or a new unit, but the current battery/unit clearly is not working properly to drain the battery in one week.** Thank you.
