Issues after Servicing

I was wondering if anyone has experienced issues after having their watch serviced by JLC in Switzerland.

I had a Master Grande Reveil sent in following a warranty issue and it has come back losing time significantly every day after just 5 months.

I also had a Master Compressor Geographic serviced and now the crown that is for the hour setting doesn't engage properly.

I am surprised at how this has turned out so would be keen to hear feedback.
