You should take it back to the cleaners. Their work is unacceptable as you're still not able to wear the blouse.
Here's how I handle grease stains. Pre-treat using Fels Naptha laundry soap. It's a bar soap so I wet the area and rub it on, scrub lightly, then let it sit for a few minutes. Wash and dry as usual. If there's a greasy/oily spot after washing I apply cornstarch or baby powder, rub it in and leave it for a day or two. When the cornstarch/baby powder is brushed off the oily spot is gone.
