Just had an oil change at dealer and have a question

Hello,
I recently had an oil change at the dealership. I asked them for new wiper blades as well. In the past they have always been the blade inserts that slide into the metal frame. This time the dealership replaced the entire metal frame with some cheap plastic replacement blades. I didn't notice at the time, but did after it rained the past 2 days. I am going back to the dealer on Saturday morning. Is this a new thing dealerships are doing (none of the old types available), or did they just pull a fast one on me?
Any feedback would be appreciated.
Thanks.

 

Cheaper to replace the whole thing. I havent seen just the refill available in a long time.

 

refills are pretty much non existent.

 

Joe is correct. THey will not always put OEM ones in either. Cost cutting

 

This is good to know b/c I was gonna ask this to be done soon. I think I'll just go get some Trico Flex Wipers
