Ring stick up cam 3rd generation not working

Hi I bought a new stick up camera (3rd gen) in April 2025. We had one that was brilliant so we wanted another. It worked brilliantly for 6 weeks now it won’t work at all. We’ve recharged the battery, it flashes once and then have no lights showing on the camera when inserting the battery - followed all instructions but nothing So thought we would delete the device and reinstall - now going through instructions to reinstall there are no lights even when pressing the setup button. Has anyone else had this problem ? Could it be the battery or the camera ?? I would like your thoughts Can’t get through to customer service in UK as in Spain and my Spanish not good enough for a conversation over the phone to Spanish number- is there an email address? I’ve tried the chat but it’s just a bot
