How about some details? If it is straightforward, they will have a warranty of probably a year on parts and labor, and should re-do the problem. But if it is something like fixing an oil leak, they should have said they fixed one or two problems, and there could be others on an older car, etc. You might have more things wrong.
It's possible that they are just going down the list of usual suspects to replace parts and hoping (or maybe not hoping) that it fixes the issue. A less reputable shop will start with the most expensive thing that is even remotely connected to whatever the issue may be.
It's quite possible that this is the situation.

What do you mean, a deep noise? Deep in the engine? Transmission? Over bumps? At idle? At higher speed?
Anyhow, go talk to the manager and tell them you feel you paid to eliminate this noise and it is still there, and see what they offer to do about it.

If the noise is constant with the speed of the car it can be tires, which get scalloped and make singing or humming noises which can be difficult to diagnose sometimes.
If it is mainly under acceleration, an axle or u-joint can cause the noise. But there are other things, transmission, water pump, alternator, internal engine, many possibilities.
Is it a knock, ping, buzz, humm, rattle? Do you feel a vibration in the steering wheel when this happens? Is it constant, or intermittent?
And what did the shop repair-was it an attempt to cure the noise?

It has a V-8. That's the engine idle you're hearing.

Tires can get worn on the edges, called "feather edging" where little raised edges are above the surface of the main part of the tire. You usually can feel this by running your hand over the part of the tire that should be in contact with the road. Or ask at a tire store to check for this.
Alignment, shocks or more often, running the tires underinflated can cause this uneven wear, and they start making "road noise."

Actually this sounds like something that happened to my daughter's Toyota Corolla. It would make a rather loud obnoxious noise that seemed to be correlated with road speed (not engine speed). Sounded almost like a tire was rubbing on a fender well, but that wasn't it. Anyway, it turned out to be a bad wheel bearing. Thankfully, the repair place nailed it the first visit

It sounds like they thought the right front hub/bearing assembly was the source of the road noise. I don't know why the alternator was replaced, but it may have been failing. Alternators can make noise, or they can fail electrically.
Back to the road noise-first, it is difficult to diagnose, as tire noise sounds just like wheel bearing noise, at first. Eventually the wheel bearing becomes very noisy. They both increase steadily with the speed of the car.
The problem is telling the two apart. Rotating the front tires to the back usually makes the noise change, if the noise is tires, and a good technician can usually feel the rough edges on tires and believe that the tires are the source of the noise.
Then on the test drive, what you do is swerve back and forth from one lane to another (it is best to pick a fairly traffic free situation for this). If the noise is tires, the noise won't change. If the noise is a front wheel bearing, the noise will get louder in one direction and go away or be substantially quieter in the other direction.
Then once you have decided the noise is a wheel bearing the real problem is deciding which wheel bearing is bad. Inside the car, the noise is difficult to pin down. It is an educated guess as to which one is bad. Sometimes the back bearings sound like the front, and the left like the right. Usually you can't feel anything with the car on the lift, although sometimes you can.
And sometimes both front ones make noise, because they are both the same age. You may replace one which needed replacing, and find the other also makes noise.
The shop should have explained this to you, and said they believe that one side makes noise, but sometimes the other may have to be replaced as well. Maybe they felt more "play" or looseness in one side by wiggling the axle by hand.
But maybe they just replaced the wrong bearing and you still have the noise.
You should discuss this with the manager and see if they will insist on replacing the other front bearing, or it they feel they may have made a mistake in the diagnosis.
They may not take the time to take the car out to test drive the way it should be, and it takes an experienced person to try to isolate this particular noise-not one of the easy things in auto repair.

Go ask Christian Bros if they feel they misdiagnosed the noise, but they may say they want to replace the other front hub/bearing. If you feel they are not responding to your concerns properly, go elsewhere.
