Did you measure oil pressure with mechanical gauge?

That could be due to the brand of oil they used. I can't explain why but some cars just don't like some oils. It could also be that the fresh oil loosened up some sludge inside and now it's restricting the oil pick up. I would try changing the oil again with a different brand. If that doesn't help, replace the oil sender just to make sure it's telling you the truth.
