False invoice given for old product charged to me by HOA

I'm irked:

My HOA had the smoke detector in my condo replaced. I was billed over $1k for the work. (I posted about this before, but now I have more facts.)

When I asked for a copy of the invoice, I was given (1) one invoice for labor and (2) an email from the repair company to the property manager, stating, "We used a smoke detector that we already had, so we didn't buy a new one. The owner should be billed $X." Since the smoke detector was old, no invoice was given for it.

The property manager then, over a week later, sent another invoice to me: an invoice for a new smoke detector. The invoice listed the same price as shown on the email specifying the charge for the old smoke detector.

So:

Problem #1: I was given an old smoke detector and was charged a brand-new price.

Problem #2: I was given a fake receipt, as though the smoke detector was newly bought, which isn't the case.

How mad would you be about this?

I would want to know the date stamped on the smoke detector the repair company "already had." It's possible that the detector the company "already had" is a new one the company had laying around.

A quick google lookup speaks about a 10 year sealed unit OR new hard wire installation is required in NY since April 2019. New CO and smoke alarms have been required for condos, too.

I thought that was common practice in New York.

Thanks. The invoice was forwarded by the condo management company, but it's on the repair company's letterhead.
