warranty claim denied on technicality — what are my options?

On mobile so apologies for formatting. Looking for advice on a legal issue. Here's what happened.

warranty claim denied on technicality. I've been dealing with this for about 8 months now and the situation isn't improving.

The contract was signed 6 months ago. I am not sure I have the original signed copy. The total amount in dispute is approximately $54,000 tbh.

Am I overthinking this or is this a real legal issue worth pursuing?

This happened to me too. Have you tried filing a complaint with the relevant agency? In my case they investigated and it got resolved without needing a lawyer.
