Stick up Cam doesn't record

This has been, by all means, the most frustrating situation. I purchased the stick up cam based on the good reputation of Ring. Unfortunately, the stick up cam choose what to record. For sure, it doesn’t record at night, when probably you need it most. During the day, records whenever feels like it.
I contact tech support and they told me that my signal was not strong and that I need it to get an extender, which I did… but guess what? STILL DOESN’T RECORD.
Any other suggestions, besides returning the camera?
