Help! I'm getting constant messages to buy a plan - I ALREADY HAVE A PLAN

I'm getting sick of the constant bright orange messages on my Ring app, every time I do any action a box pops up to say 'Your trial ends soon... etc' I have had a full Ring plan for a long time but every time I add a new camera it triggers this crazy monthly long cycle of orange messages and free trial plan warnings. Can anyone help get rid of these please? I have phoned Ring customer service, they were absolutely useless, told me yes, this will happen for a month every time you add a camera, and no they couldn't do anything about it, basically just accept it, goodbye. I asked if I could speak to anyone else or raise a complaint about it, but was told they don't accept any complaints and they have no complaints department and no, I couldn't escalate it. It makes it super awkward to use the app and just very annoying. I check the app several times a day and am having to constantly dismiss the warnings. Customer service was really poor, any ideas?
