99 Ranger - Clutch problem???

I just had a new clutch kit, pilot bearing and slave cylinder installed on my 1999 Ranger XLT 3.0. After the install I am still hearing a bearing chattering away. I took it back to the shop that installed it and they said it's normal. I've put on maybe 1000 - 1500 miles on it since and it seems to be getting louder. My question is..... should it still be making this noise?

a little noise at first is normal, not getting worse!!! take it back and demand it fixed!!!

That's what I thought. If anything it should have gone away. I'll be going back to them tomorrow. Thanks.
