Is it a fungus or something else?

Need closer images. Looks like glare from this distance.

FYI

I believe you have 2 fungi at work. Black Spot and mildew. I think the Black spot fungus started first and weakened the plant and then mildew started.

What should i do about it?

I got this plant today. Should I bring it back? Is this problem cureable?

What should i do about it?

If the plant is decidious the leaves will soon start to fall. Rake them all up and burn them. Remove any mulch from around the base of the plant and burn it too. If the plant is evergreen remove ALL affected limbs and leaves and burn them. Then spray with a copper spray. Replace mulch. In the spring liberally sprinkle horticultural cornmeal all around on the ground and on the plant numerous times during the year and also spray with copper to prophylactically reduce the chance of this stuff recurring.

I'd take it back. That is a sick plant but it is curable. Is it a rose of some sort? If it is many roses are susceptible to black spot.

It is a Drift rose.

It is a Drift rose.

The leaves will soon fall off. I presume it is in a pot? If so, when all the leaves fall off take it out of the pot and wash away all of the soil and dispose of it. Repot with fresh soil and a different container or place in the ground.

Thanks for the info but I will try to return them.

Just remember that the spores of both mildew and black spot live in the soil and are spread by splashing water and wind. Keeping this in mind it is probable that every plant in the store has these diseases even though the plants might show zero sign of it.
