Removing old account, I don't know who the previous owner was.

I'm having an issue that your customer support team couldn't even help me with I called to see if the camera that I purchased from an estate sale was an indoor outdoor camera and gave them the serial number they couldn't tell me whether it was or was not I had to look it up online well I called to see if they could remove the old account because no one knows who the previous owners information is for this account and y'all can't remove an old account through your internet service or whoever provides your internet but I wasn't at all surprised because your customer service going to tell me if I had an indoor outdoor camera I just need to know is there any way to remove account if you don't know that person's information or there are no longer living I want to use the camera cuz we're going out of town and it looks like it'll be a great little camera with the app but if I can't remove it on account and you can't remove an old account and you couldn't even tell me whether it is an indoor outdoor camera is there hope at all that anyone can help me thank you
