For thinking to report my former employer to trading standards

[Terribleluck]

My former employer is selling something that it's not as advertised, and they're still advertising with old screenshots that don't even exist! I know most of the customers would have a case, but I think the way they run is so unethical. I think in the end I wouldn't do it as I don't want to leave my ex-collegues unemployed (as I'm sure the company would go down), and I'm sure my employer would think it was me who told TS.

I'm sure if the issue is significant enough their customers will report them soon enough assuming they don't end up refunding most purchases

Unless their product is potentially dangerous, I'd be inclined to leave them be.
Customer feedback will, ultimately, be their downfall.
