Corrosion in doorbell

Cannot fit plug into my door bell. So it obviously cannot be charged.
Sent pics and they said it was corrosion inside plug which is problem. Said I needed a new ring and since i bought it in 2019 it is out of warranty so most they will offer is 35 percent off. Why would I want to pay for ANOTHER defective cheap product? Googling this I see it happens to mutitudes of others. And customer service knew exacytly what it was.

Shouldnt a ring last for more than 2-3 year in a covered location? Cheap and inferior product obviously.

I have rings at two homes, pay for monitoring and this is horrible.
How can you get away with this.

Sell something inferior

You then want me to pay for a other one.

Ridiculous. Never ever again.
