Ecoboost clutch problem

[jimh125]

I have 1.0 ecoboost 2012 clutch and dual mass flywheel and slave cylinder replaced 18 months ago by local garage, then a few weeks ago had the pedal staying to the floor so same garage diagnosed the slave cylinder faulty so they replaced it for second time now pedal feels soft and biting point is low I went back to garage and complained but they say it's normal and I said the first slave cylinder shoukd of lasted longer than 18 months now they won't answer my calls, can anyone help as I'm worried the clutch is going to go again as it doesn't feel right.
