Is my engine oast?
At about 13,000 miles, the oil pump on my 2010 Coupe decided to die. The symptoms were pretty obvious: chuga-chuga sound from the engine, zero oil pressure, no power, ticking lifters. I instantly turned off the engine and had it towed to the dealer for repair under warranty. Although distressed that stuff happens, I just left it to the service people to fix it.
They noted some scoring in the bore but otherwise ok and replaced the oil pump.
Now, 2000 miles later I discover that they DID NOT REPLACE THE OIL AND FILTER but just topped off the oil!!! I am just heartbroken that this could have inflicted permanent damage to the engine. Is it possible to replace an oil pump without draining the oil? Am I being overanxious? Suggestions please.

I think you need another engine. That one could be oast.
Seriously, though, I would be very unhappy with the situation. If it was under warranty, in some ways it would have been better to drive it until it seized.

Are you sure they didn't replace the engine oil? The FSM procedure for replacing the oil pump when there is no oil pressure is to pull the oil pan as the oil pump, screen and crankshaft oil deflector all have to be removed/cleaned/replaced. I doubt they would have just replaced the oil pump alone when the procedure clearly defines what they have to do. Check the repair bill to see what operations were done.

I doubt that any tech would not replace the oil & filter as the oil pump has to be primed too. If there was damage to the bearings you would see a drop in oil pressure.
My concern would be how much and how bad was the scoring

First thing I would do is an oil analysis.

That will tell you alot, let the Blackstone people know your situation. They can tell you if damage was done. If you change your oil, keep your filter and or cut it open for more evidence.
A lousy tech can and may replace the pump without lowering the pan or changing the oil.
Most are great guys and would not do this, but service writers & managers can and do pressure techs.
