Need help: Stuck with a ring doorbell from a previous owner I can't use

Hello guys,I just bought a new house and the previous owners had a ring doorbell. I'd like to use it as well, however when I try to connect that doorbell to my newly created ring account it tells me that the device is still linked to the previous owners.I contacted the previous owners to unlink the device from their account, however they are not that helpfull. They keep telling me they have deleted it. They also ignore my questions or my request to help them.I called support for help but all they tell me is contact the previous owners.Any similar experiences or tips on what to do next?The only thing I see as an option is buy a new device..Thanks in advance!
