Non performing Wyze cam and Pan

I have 2 wyze cam v2 and a wyze cam Pan all installed outdoor. Since last few months getting no notification or wrong notifications. Many times notification for person but no person. Shared many such videos with wyze, called and chatted with tech support. Still the problems exist. Now, they want us to pay for services which were promised free. I am not sure if I should subscribe for Cam plus as the same was not effective during the trial. Is there any hope that wyze can provide dependable service or I should junk the system?
Please advise
