Floodlight strobing and one bulb gone

Hi, I had a floodlight camera installed in August 2020 which I have a receipt for. Over a week ago, one of the lights stopped working. A few days later, the light is now flashing on and off when motion is detected. I called ring customer services and went through the troubleshooting steps, but it’s still the same. I was told that I’m not entitled to anything apart from a discount code to purchase a new camera as it’s over the 2 year warranty period. I don’t understand how customers can be treat like this.. especially when I have multiple items with yourselves and a monthly subscription fee. It’s also unfair that I have to pay money for an electrician to do the work again (during a cost of living crisis!) The camera has been up for 3 years and 3 months.. electrical products should last atleast 5 years, so this is unacceptable. After doing some research on your forums, it seems many other people have had the same issue around the same time..therefore this is a common fault that hasn’t been addressed by you, you just expect customers to purchase new cameras… I’ve contacted trading standards, and I would like to know how you are dealing with this fault? There is no complaints procedure in place.
