Basic Plan Owner But My Video History Doesn't Save

Hi, I'm the owner of a Ring Spotlight Cam with a basic plan subscription attached but my video history continuously disappears much earlier than the stated 60-day video history. The videos disappear in seemingly random cutoffs. For example, I had accumulated video clips for the last week but it randomly disappeared last night. Now, again, the video history from last night to tonight disappeared, leaving me only with one motion detection clip recorded an hour ago. I'm a U.S. based customer. If you are going to respond by asking me to contact customer support via telephone, please also include the hours of operations. Thank you.
