Two dead chimes

We have a first and a second generation Chime and neither works. The newer one will not even light up no matter where I plug it in and now that I removed it from the network I cannot reinstall it. The first generation has a blue light but no amount of button pushing makes it flash and it is offline. The ring tech says buy new ones. First, after reading the complaints like mine, why throw out another $60? And by the way, they are out of stock. Call us unhappy.
